CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of PCT Application No. PCT/AU2016/000194, filed Jun. 7, 2016. PCT Application No. PCT/AU2016/000194 claims the benefit of priority from prior Australian Patent Application No. 2015902144, filed Jun. 9, 2015, the entire contents of each of which are hereby incorporated by reference for all purposes. 
    
    
     FIELD OF INVENTION 
     The present invention relates to the field of pillows or cushions. 
     In one form, the invention relates to a portable cushion for supporting for a user&#39;s head, neck, shoulders or upper body to enable comfortable resting or sleeping when the user is sitting in an upright or forward position. 
     It will be convenient to hereinafter describe the present invention in relation to a seated user who is travelling by air, road or rail however it should be appreciated that the present invention is not limited to that use only. The present invention also has a wide range of applications wherein the user is stationary. By way of example the present invention could be used in a medical application where a patient is required to sit still in a relatively forward upright position while a procedure is being carried out, or because they have a condition that makes lying down inadvisable. 
     It will be further convenient to hereinafter describe the present invention as a support considering that such support is cushioned or configured to provide comfortable surfaces to engage with the travelers head or other part of their body. The support is portable however it may also be removably attachable to a further supporting non-portable device or structure such as a seat. 
     BACKGROUND ART 
     It is to be appreciated that any discussion or documents, devices, acts or knowledge in this specification is included to explain the context of the present invention. Further, the discussion throughout this specification comes about due to the realization of the inventor or the identification of certain related art problems by the inventor. Moreover, any discussion of material such as documents, devices, acts or knowledge in this specification is included to explain the context of the invention in terms of the inventor&#39;s knowledge and experience and, accordingly, any such discussion should not be taken as an admission that any of the material forms part of the prior art base or the common general knowledge in the relevant art in Australia, or elsewhere, on or before the priority date of the disclosure and claims herein. 
     Many travelers are required to sit upright for long periods of time. Due to seating arrangements and space constraints they are unable to lay horizontal or near horizontal to facilitate comfortable sleeping. Often this results in tiredness, pain and discomfort with negative affect on the traveler&#39;s health and wellbeing. 
     Similarly, the nature and environment of travel provides vibration, bumps, noise and other interruptions to rest or sleep that are not usually experienced in a resting or sleeping environment. In an effort to gain extra comfort, travelers typically use U shaped pillows or adjustable flaps built into an airline seat to support the head from falling left, right or to the rear. However these devices rely on the head and body to be oriented rearward, resting on the seat back and they will not stop the head from falling forwards. 
     In an attempt to find a comfortable position when seated an airline traveler may try leaning forward and bracing their head in their hands. This is not sustainable as the arms relax as the traveler falls asleep and the brace collapses. Similarly a traveler may rest their head on a stack of pillows or other makeshift support items on an outwardly folded tray table, however this position may not be particularly comfortable for a sustainable period. Some devices, such as the device described in U.S. patent application 2003/0167571 provides a support that rests upon a tray table extending from the back of an airline seat so that a traveler to sit in a relatively forward upright position. However these types of devices are often unsuitable in confined spaces, such as the economy section of an aircraft because they are large in volume and cumbersome. Furthermore, devices of the prior art that require support from the tray table fixed to the seat of a passenger in front typically move if the passenger in front moves. This tends to disturb the traveler using the support. 
     Sustaining a seated position for extended periods is not only uncomfortable but can cause neck injuries or soreness to the traveler. In particular, sleep or comfortable rest can be difficult to achieve in aircraft when a traveler is required to sit in a relatively upright position in an environment that is noisy, vibrating and punctuated by disturbances due to aircraft movement and the activities of passengers or crew. 
     Given the nature of upright and seated travel, travelers may also take sleeping pills or similar and such drugs may cause drowsiness or other side effects. In the case of an emergency these side effects may limit the traveler&#39;s ability to react appropriately to avoid injury or life threatening situations. 
     In addition, travelers often use miscellaneous aids such as headphones, ear plugs, eye masks and other items. Travellers often pack such aids into carry-on baggage that is stored in overhead lockers or under their seat making them inconvenient to access. Furthermore, the aids often become lost, disorganized or are simply inconvenient to carry. 
     SUMMARY OF INVENTION 
     An object of the present invention is to provide a device that improves sleep or rest in the seated position. 
     Another object of the present invention is to provide a means for improved sleep or rest for road, rail or air travelers. 
     It is an object of the embodiments described herein to overcome or alleviate at least one of the above noted drawbacks of related art or to at least provide a useful alternative to related art. 
     In a first aspect of embodiments described herein there is provided a support comprising:
         a first pillow comprising a first pillow body having a first arm and a second arm,   a second pillow comprising a second pillow body having a third arm and a fourth arm, the first and third arms being attached to a first joint, and the second and fourth arms being attached to a second joint wherein the first and second pillows can be rotated about the joints.       

     The first pillow and second pillow may be discretely connected or integral at the joints but must be able to be rotated about the joints by bending (if integral), or by virtue of inclusion of a hinge or other rotatable mechanism. When the first pillow and second pillow are integral the first joint and the second joint may be, for example flex points wherein the degree of rotation around the joints can be adjusted and releasably locked using a locking mechanism. 
     Typically each of the first pillow and the second pillow has an internal surface and an external surface. The support has a first, fully ‘closed’ position in which the two internal surfaces are pressed together and are in contact over most of their surface area. The support also has a second fully ‘open’ position in which the two internal surfaces are not in contact. The support can be changed between the fully open and fully closed positions by rotation about the joints. 
     In use at least one of the external surfaces is in contact with the user&#39;s body, typically their face if they are at rest. 
     In one embodiment of the present invention the first pillow and second pillow are of complementary size and shape. In another embodiment of the present invention the first pillow and the second pillow are of different sizes or shapes. for example, one pillow could be conformed to fit within a recess in the other pillow. 
     The pillows may be made of any material suitable for bearing the weight of a person at rest, and subject to the user&#39;s personal preference with regard to pillow softness and density. In a particularly preferred embodiment the pillows are made of expanded polymeric foam, such as memory foam, expanded styrene beads of foam pieces. Alternatively the pillows may be inflatable. The pillow may be constructed of any number of materials. For example, the pillows may have relatively soft or low density material encapsulating a higher density material that is configured to give shape and structural support to the pillow. 
     One or both pillows may comprise a rigid structural support located internally or externally to the pillows. In a particularly preferred embodiment, the rigid structural support is internal to one or both pillows and is generally U-shaped with each end located adjacent one of the joints. 
     In a particularly preferred embodiment the first pillow and the second pillow are U-shaped but the pillow shapes may vary for purposes such as styling, additional comfort, or for better spreading of any load imparted to the pillows by the weight of a user. 
     In the second aspect of embodiments described herein there is provided a support comprising:
         a first pillow comprising a U-shaped pillow body having a first arm and a second arm,   a second pillow comprising a U-shaped pillow body having a third arm and a fourth arm, the first and third arms being attached to a first joint, and the second and forth arms being attached to a second joint,
 
wherein the first and second pillows can be rotated about the joints and configured to receive the front of user&#39;s neck between the first and second arms and the user&#39;s head can rest in a forward position on the first pillow body.
       

     In this manner the user can rest their head in a forward position, the pillow comfortably resting the weight of the user&#39;s head without them being required to provide assistance with their arms, hands or any other part of their person. 
     The support can be adjusted to support the travelers head as it tilts to the left, right, rear or forward position or any position in between. 
     Pillows 
     The shape and configuration of the support can provide clear space for the traveler to breathe when head rests on the first pillow, their face being located in the U-shaped void defined by the pillows leaving the user&#39;s nose and mouth unobstructed. 
     As such, the support of the present invention has multiple modes of use some of which are describe and depicted herein. These modes are possible by virtue of the support enabling a user to better use the space available in and around their seat in order to find their most optimum comfort position. Travel pillows of the prior art doenot offer as many different options. 
     Harness 
     In another preferred embodiment, the support includes a harness. Typically the harness is in the form of a strap of adjustable length having ends adapted for removable attachment to the support. For example the adjustable strap may be attached by buckles or Velcro adjacent the joints. 
     It will be readily apparent to the relevantly skilled person that it would be optimum to have a seat configured for ready attachment to the pillows or the harness. 
     The harness may be used in several ways. For example, the harness may be used to retain the support around the user&#39;s seat back or neck so that it does not fall when the weight of the travelers head is lifted from the support. Alternatively, the harness may be used as a shoulder or neck strap for carrying the support when not in use and leaving the user&#39;s hands free for carrying luggage and for other tasks. 
     Joints—Rotation 
     The first joint and second joint may be integral with one or both pillows. Alternatively the joints may be removably attached to one or both pillows. 
     Preferably the joints are configured to allow the angle between the first pillow and second pillow to be adjusted and then releasably locked in a desired position. For example the support may include a releasable locking mechanism so that the degree of rotation of the first pillow and second pillow about the joint can be releasably maintained. The ability to lock the pillows into position is particularly useful for providing support to the user&#39;s head and body in a forward upright or rearward upright position when the user is seated. 
     In one embodiment the joint is rotatably adjusted using a ratchet mechanism or screw thread mechanism. In another embodiment the joint is spring loaded and self locking. 
     Joints—Extension 
     In a preferred embodiment each joint is extendable. In a particularly preferred embodiment each joint comprises a hinge with one, or two extendable leaves. For example, one or both leaves may be in slidable arrangement with a frame that can be extended from the leaf and then retracted relative to the leaf. 
     Each leaf and any associated frame may independently, be embedded within a pillow, or adjacent an external surface of a pillow. Preferably the frame, or frame in combination with the leaf is capable of providing structural strength to the support and is capable of bearing some of the load imparted on the pillows. 
     Preferably the joints are configured to allow the extension or retraction of the joint to be adjusted and then releasably locked in a desired position. For example the support may include a releasable spring loaded locking mechanism. 
     Thus in a third aspect of embodiments described herein there is provided a support comprising:
         a first pillow comprising generally U-shaped body portion having a first arm and a second arm,   a second pillow comprising a generally U-shaped body portion having a third arm and a fourth arm, the first and third arms being attached to a first joint, and the second and forth arms being attached to a second joint,
 
wherein the first joint and the second joint are extendable.
       

     The extendable leaves allow the pillows to be moved apart, varying the distance between them at least in the vicinity of the joints. Thus the user has the ability to (i) vary the degree of rotation of the pillows around the joints, and (ii) vary the separation between the pillows in the vicinity of the joints. This provides a user with myriad options for positioning the pillows and supporting their upper body. 
     Storage 
     In another preferred embodiment the support is adapted to provide storage for example for the harness or a removable joint. For example a storage area may be provided as a recess in one or both pillows. 
     Alternatively the storage recess may be in the form of a pocket or other receptacle that is integral, or removably attached to the support. The storage recess typically includes a suitable closure such as a zipper or flap secured by Velcro. 
     Modes of Use 
     There are multiple modes of use of the support of the present invention which will be apparent from the description and drawings herein. 
     In a fourth aspect of embodiments described herein there is provided a method of using a support, the support comprising:
         a generally U-shaped first pillow having a first arm and a second arm extending from a first pillow body,   a generally U-shaped second pillow having a third arm and a fourth arm extending from a second pillow body, the first and third arms being attached to an extendable first joint, and the second and forth arms being attached to an extendable second joint,
 
wherein the method comprises the steps of:
   (a) rotating the first and second pillows about the joints,   (b) optionally extending the first and second joints,   (c) locating the front of user&#39;s neck between the first arm and second arm so that a user&#39;s head can rest in a forward position on the first pillow body, and   (d) locating the second pillow on a surface to support the weight of the user&#39;s head.       

     The weight of the user&#39;s head resting in a forward position on the first pillow body can thus be dispersed to the second pillow and then onto the surface on which it rests, such as the user&#39;s shoulder, user&#39;s torso, horizontal surface such as a table top or chair arm, vertical surface such as a wall. 
     The method of use may further comprise the step of connecting a harness between the support and the user, or structure for bearing part of the load. 
     Other aspects and preferred forms are disclosed in the specification and/or defined in the appended claims, forming a part of the description of the invention. 
     In essence, embodiments of the present invention stem from the realization that a travel pillow can be configured to better support the weight of a user&#39;s head when they are confined in an upright sitting position for extended periods of time. The configuration of the travel pillow can be angled or extended to provide more options for the user to comfortably orient themselves in a forward sitting position within a limited space such as an airline seat. 
     Advantages provided by the support of the present invention comprises the following:
         ability to support the head, neck and first body in a relatively forward position when sitting;   can be used in a multitude of travel applications in aircraft, trains, buses, cars, boats, in addition to other non-travel related applications such as sitting at an office desk, or during medical procedures where patients are required to have their body upright, or any other situation requiring an upright sitting position;   is portable and can remain comfortably placed around the neck while a user is walking, such as between transit services, thus providing free hands to carry other items;   may be attached to a secondary non-portable device or structure to provide additional support to the user;   provides an additional and improved level of comfort and increases the user&#39;s likelihood of gaining sleep when compared to devices of the prior art designed for this said purpose;   allows a user to make the best use possible of the space around them, even very confined space; by enabling them to bend forward, or to either side;   may be worn by the traveler and therefore not considered to be carry-on or check-in luggage;   provides all the advantages of a conventional U shape pillow of the prior art;   can be used to carry, organize and store various accessory &amp; travel related items.       

     Further scope of applicability of embodiments of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the disclosure herein will become apparent to those skilled in the art from this detailed description.

     DETAILED DESCRIPTION 
     Embodiments disclosed herein provide a portable support for a user&#39;s head and neck which can be used in multiple modes. 
     In a particularly preferred mode, the user&#39;s head and neck are supported. This first mode of operation is not dissimilar to a conventional travel pillow whereby the traveler positions the support on the shoulders and around the neck. 
     In another preferred mode, the user&#39;s head, neck, shoulders and upper body are supported. This second mode of operation enables the user to open the two pillows of the support to an angle which provides a comfortable resting or sleeping position whereby the user&#39;s face, head, neck, shoulders and upper body are supported relatively forward of the upright seated position thus providing a comfortable position for sleep or rest. 
       FIG. 1  depicts a side view of one embodiment of the support  8  of the present invention suitable for portable use during travel. In this view the support  8  is in the closed position with the inner surface  1   a  &amp;  7   a  of each pillow  1  &amp;  7  in abutting relationship. The pillows  1  &amp;  7  are connected by jointed hinges  4   a  &amp;  4   b  which are tightened and locked by rotating either or both of the knobs  5   a  or  5   b . In the closed position, the support  8  is compact and portable and readily stored or carried. 
     In this embodiment the first pillow  1  and second pillow  7  are of the same shape and dimensions. It can readily be seen that each pillow has a body and two arms. The end of each arm terminates at the hinge  4 , thus connecting the two pillows  1  &amp;  7 . 
       FIG. 2  depicts the support  8  of  FIG. 1  from the front. In this view the first pillow  1  can be readily seen, and obscures from view the second pillow  7  which is directly behind. The pillows  1  &amp;  7  in this embodiment are generally U-shaped and define a space  2  for receiving a travelers face, head and neck. The hinges  4   a  &amp;  4   b  are folded and locked so that in this view the support  8  is maintained in the closed position. Each hinge  4   a  &amp;  4   b  has two leaves  10   a ,  10   b ,  10   c  &amp;  10   d  ( 10   a  &amp;  10   b  associated with the first pillow  1 ;  10   c  &amp;  10   d  associated with the second pillow  7 ). Each of knobs  5   a  &amp;  5   b  can be rotated in a first direction to lock the hinge to which they are respectively attached. 
     When the knobs  5   a  &amp;  5   b  are rotated in a counter direction the restriction on their respective hinges  4   a  &amp;  4   b  is reduced and the angle between the pillows  1  &amp;  7  can be adjusted according to the desired support position of the traveler. In this embodiment the frames  9   a  &amp;  9   b  can be extended from the leaves  10   a  &amp;  10   b  of the joint hinges  4   a  &amp;  4   b.    
     The U-shape  3  formed by the pillows  1  &amp;  7  allows the user to position the support  8  on their neck and wear the support  8  as they board or disembark from an aeroplane, train or bus or when they are in transit, as well as providing head and neck support while seated relatively upright. 
       FIG. 3  is a side view of the support  8  in the open position. In this view the hinges of the joints  4  have been rotated, moving the pillows  1  &amp;  7  to a 180 degree angle of separation at the joints  4   a  &amp;  4   b  as compared with the closed position shown in  FIG. 1 . The hinges of the joints  4   a  &amp;  4   b  have been adjusted by rotating their respective knobs  5   a  &amp;  5   b  as described with reference to  FIG. 2 . 
       FIG. 4  is a front view of the support  8  as shown in  FIG. 3 . In this view the hinges of the joints  4   a  &amp;  4   b  are both visible. Each joint hinge has a leaf  10   a  &amp;  10   b , each of which has an extendable frame  9   a  &amp;  9   b  which in this view is shown adjacent an internal surface of the first pillow  1 . The extendable frames  9   a  &amp;  9   b  are inside the pillow and therefore cannot be seen. In other embodiments of the support however, other arrangements of the hinge leaves and extendable frames may be used, such as having all leaves and frames located inside the pillows, or all located on surfaces of the pillows, or a combination of the two. The buttons  6   a  &amp;  6   b  are configured to engage with the leaves  10   a  &amp;  10   b  to actuate extension or locking of the frames  9   a  &amp;  9   b .  FIG. 4  depicts the frames  9   a  &amp;  9   b  in the fully retracted position which brings the pillows  1  &amp;  7  together in abutting relationship and the ends of their arms. 
       FIG. 5  depicts a side view of the support  8  with two pillows  1  &amp;  7  with the joints  4   a  &amp;  4   b  adjusted with their respective pairs of leaves  10   a  &amp;  10   c  and  10   b  &amp;  10   d  at 90 degrees. The frames  9   a  &amp;  9   b  of leaves  10   a  &amp;  10   b  have been extended following pressing of the buttons  6   a  &amp;  6   b  of the actuators, sliding along their respective hinge leaves  10   a  &amp;  10   b  so that a user can achieve any desired position between full extension or full retraction of the frames  9   a  &amp;  9   b.    
       FIG. 6  depicts a front view of the support  8  with the two pillows  1  &amp;  7  and the pairs of joint leaves  10   a  &amp;  10   c  and  10   b  &amp;  10   d  adjusted to a straight angle of 180 degrees. This embodiment depicts the joint leaves  10   c  &amp;  10   d  located fully inside the second pillow  7  while the leaves  10  &amp;  10   b  are exposed with the frames  9   a  &amp;  9   b  extended. Actuation of the knobs  5   a  &amp;  5   b , and buttons  6   a  &amp;  6   b  is required to adjust the respective frames  9   a  &amp;  9   b  and hinges  4   a  &amp;  4   b  as previously described. 
     This embodiment of the support further depicts a storage space  11  with a closure  12 . The storage space  11  may be used for any miscellaneous item however typically it is used for the storage of travel related items, headphones, ear plugs, eye mask, pen, batteries and the like. 
       FIG. 7  depicts a side view and  FIG. 10  is a perspective view of the first mode of use of the support  8 . In the first mode the two pillows  1  &amp;  7  are closed against each other with their inner surfaces ( 1   b ,  7   b ) pressed together. The support  8  is located around the neck of the seated user  14  in a position typical of a conventional U shaped travel pillow. The traveler  14  is able to shift their position to rest their head  15  against the support  8  or the seat  19 . In this mode the user  14  does not have support for the head  15  if the weight of the head  15  shifts forward away from the seat  19  because the U-shaped opening  3  defined by the pillows  1  &amp;  7  provides no support in that area. 
       FIG. 11  depicts a second mode of use wherein the support  8  is more open with the joint  4  is locked to maintain an acute angle between the two pillows  1  &amp;  7 . The user can rotate the support around their neck to the desired position, resting the pillows on the seat. 
       FIG. 12  depicts a third mode of use, the two pillows  1  &amp;  7  are opened and the joint  4  is locked to form an acute angle about the joints  4   a  &amp;  4   b . The second pillow can be rested on a flat surface such as a bench or tray table extending from the rear of an aeroplane seat. Typically the user will place their forearms between the first and second pillow. 
       FIG. 8  depicts a fourth mode of operation of the support  8  in a side view.  FIG. 13  is a perspective view of the fourth mode of operation of the support  8 . In this mode the two pillows  1  &amp;  7  are in an open position. In this mode the user has their head  15  against the outer surface  1   a  or the first pillow  1  and their chest against the outer surface of the second pillow  7 . The weight of the travelers head, neck and upper body is downwardly pressing against the pillow  1  in which the frames  9   a ,  9   b  may optionally be extended from the joint leaves  10  (not visible) providing a comfortable sleeping or resting position. Extending the frames may be particularly desirable, for example, for very tall users. The weight is also transferred to the user&#39;s  14  chest and second body through the frames  9   a ,  9   b . In this embodiment an adjustable strap  13  is located around the neck of the user  14  and attached adjacent the joints  4   a ,  4   b  of the support  8  thus preventing the support  8  from falling downward if the user  14  lifts their head  15  or shifts their body position. The support  8  may also be rested against the seat arm  16  or in further embodiments a secondary frame (not drawn) may extend from the support  8  to provide a further brace which may rest or be affixed to the seat arm  16 , seat  9  or any other conveniently located fixed structure. 
       FIG. 9  depicts a front partial view of the support  8  with the user&#39;s face  20  resting against the second pillow  7 . In this embodiment the U-shape  3  defined by the pillows of the support  8  enables the weight of the user&#39;s head to be dispersed through the support  8  whilst the space  2  defined by the pillows leaves the face  20  unrestricted so the user can breathe through their nose  17  and mouth  18 . In this view the support is only partially shown and the second half  21  of the support  8  has been omitted. The support  8  herein is positioned against the user in the same manner as described in  FIG. 8  whereby the travelers said weight is dispersed to the traveler&#39;s chest and lower body. 
       FIG. 14  depicts a fifth mode of use of the support  8  wherein the adjustable strap  13  is looped around a seat headrest or otherwise attached to the seat. The ends of the strap are attached adjacent the joints  4  of the support  8 , again preventing the support  8  from falling downward if the user  14  lifts their head  15  or shifts their body position. In this mode the user rests their face in the U-shaped recess. 
       FIG. 15  depicts a sixth mode of use of the support  8 , which is similar to the fifth mode, except that the user rests with one cheek on the first pillow. 
     The fifth and sixth modes allow the user to lean forward in a manner similar to propping their head with their hands. When used in aeroplanes, these modes provide the advantage that the person in front can angle their seat backwards without interfering with use of the support. Furthermore the user does not need to incline their own seat. 
     In a seventh mode the user loops the adjustable strap around a seat headrest, opens the pillows to form an obtuse angle at the joints and orients the support to their left or right side so the user sleeps upright with their back to the seat but with all their weight leaning sideways. 
     There are multiple other modes of use of the support of the present invention which will be readily apparent to the user and which will fall within the scope of the present application. 
       FIG. 16  depicts one embodiment of a joint according to the present invention. In this embodiment the joint can lengthen and shorten the distance between the pillows by virtue of a sliding ratchet mechanism which can be operated manually by pulling the pillows away or pushing the pillows toward each other. The ratchet comprises a tubular configuration of the leaf  10   a  which receives the frame  9   a . The frame  9   a  has two integral legs sprung outwardly with a dome shaped end (not visible) that engages with the recesses  28  to lock the selected distance position. 
     Furthermore as depicted in  FIG. 17  in this embodiment the joint can be rotated by depressing the knob  20  which is connected to a splined shaft  21  which slides through an orifice  22  drawn in  FIG. 16  and pushes the frame  9   a  to disengage the pins  29  which slide into any of the multiple recesses  30  located in the frame  9   a . When the knob  20  is released the spring  24  pushes the frame  9   a  toward the pin and as the joint is rotated the pins  29  slide back into the recesses  30  to lock the desired angle of the frames  9   a  and  9   b  relative to each other and thus setting the angle of the pillows  1  &amp;  7 . 
     It is also to be understood that the specific devices and modes illustrated in the attached drawing, and described in the specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. Additionally, unless otherwise specified, it is to be understood that discussion of a particular feature of component extending in or along a given direction or the like does not mean that the feature or component follows a straight line or axis in such a direction or that it only extends in such direction or on such a plane without other directional components or deviations, unless otherwise specified. 
     While this invention has been described in connection with specific embodiments thereof, it will be understood that it is capable of further modification(s). This application is intended to cover any variations uses or adaptations of the invention following in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains and as may be applied to the essential features hereinbefore set forth. 
     As the present invention may be embodied in several forms without departing from the spirit of the essential characteristics of the invention, it should be understood that the above described embodiments are not to limit the present invention unless otherwise specified, but rather should be construed broadly within the spirit and scope of the invention as defined in the appended claims. The described embodiments are to be considered in all respects as illustrative only and not restrictive. 
     Various modifications and equivalent arrangements are intended to be included within the spirit and scope of the invention and appended claims. Therefore, the specific embodiments are to be understood to be illustrative of the many ways in which the principles of the present invention may be practiced. In the following claims, means-plus-function clauses are intended to cover structures as performing the defined function and not only structural equivalents, but also equivalent structures. 
     “Comprises/comprising” and “includes/including” when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof. Thus, unless the context clearly requires otherwise, throughout the description and the claims, the words ‘comprise’, ‘comprising’, ‘includes’, ‘including’ and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.
