RELATED APPLICATIONS 
   This present application is continuation-in-part of application Ser. No. 10/428,319 filed on Apr. 29, 2003 entitled “METHOD AND APPARATUS FOR FLOATING INSTALLATION OF TILES”, by Poliacek, currently pending, for which the priority date for this application is hereby claimed and which is incorporated herein by reference in its entirety. 

   FIELD OF THE INVENTION 
   This invention relates generally to tile and masonry installation, and specifically to a method and framework for installing tiles. 
   BACKGROUND OF THE INVENTION 
   The building industry has long used various types of tiles in construction projects. Tiles come in many forms and are manufactured from various types of materials, in a wide variety of colors and surface textures. For example, ceramic tile is often used in bathroom applications. Marble tile is often used for flooring and other decorative applications. 
   Better techniques for installation of tiles have evolved over time. In fact, many patents that describe installation techniques have been granted. Most of these evolutions in tile installation techniques have been developed in response to the inadequacy of former installation methods. One common problem with installation of any tile is the fact that individual tiles need to be aligned relative one to another. In response to this problem, prior art methods for installation of tile include methods where spacers are introduced between individual tiles in order to ensure uniform tile installation. In fact, all of the known art addresses this major problem. Various techniques for the installation of tile spacers have been devised including the use of a pre-fabricated lattice that can be placed on an installation surface. Once the pre-fabricated lattice is installed, individual tiles may be secured into the lattice resulting in a clean, uniform installation. Of course, all of these prior art methods require the use of a mortar in order to secure an individual tile to the installation surface. Additional mortar (i.e. “grout”) is then used to fill the interspatial gap in between individual tiles. 
   These prior art methods fail to address some other major problems associated with the installation of tile in typical construction applications. One such problem is the need to easily replace an individual tile if it were to be inadvertently damaged. Yet another problem is that all known tile installation techniques apply an individual tile to a installation surface that is, in many cases, a cold concrete slab. Hence, a tile floor constructed according to conventional wisdom results in a cold, heat-sunk surface. 
   SUMMARY OF THE INVENTION 
   As already introduced in the incorporated reference, the present invention is a method for installing tiles in floating manner above the floor. The method comprises providing a support within the footprint of and proximate to the outer perimeter of a tile. A first border is provided along one edge of the tile and a second border is provided along the second edge of the tile wherein the two edges are substantially orthogonal to each other. The present method is further distinguished by the provision of maintaining the first border in place relative to the second border. 
   In order to maintain the position of the first border relative to the second border, one alternative method provides for connecting a first end of the first border to a cross-tie. Then, a second border is orthogonally connected to the cross-tie. According to the method, the first border is maintained in position relative to the second border by mating a first connector of a first type that is associated with the first border to second connector of a second type that associated with the second border. 
   In order to provide a generally pleasing aesthetic appearance, a fascia is provided between the first border and the second border. According to an exemplary method, the fascia is provided by extending the first border to a tapered transition line and also extending the second border to the same tapered transition line. 
   The present invention also comprises a tile installation fixture comprising a support rail, a border and a first connector substantially at one end of the support rail. According to one alternative embodiment, the first connector comprises a connector that is compatible with a cross-tie. According to one alternative embodiment of the present invention, the border extends beyond the support rail. According to yet another example, this extension of the border continues to an imaginary tapered extension line that extends outward and away from the end of the support rail. The support rail itself, according to an exemplary embodiment comprises a ledge that runs along the border and that is lower in elevation than the border. The installation fixture border comprises a raised surface that runs along the support rail. 
   According to an alternative example exemplary embodiment of the invention, the first connector comprises a right-angle connector of a first type. According to yet another exemplary embodiment, the tile installation fixture further comprises a second right-angle connector of a second type. This second type connector is complementary to the first type so as to enable the two connectors to mate. When so mated, the support rail and border of a first tile installation fixture is set substantially orthogonal to the support rail and border of a second tile installation fixture.

   DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1  is flow diagram that depicts an exemplary method for installing a floor tile according to the present invention. A tile support is provided (step  5 ) within the footprint of the tile is generally proximate to the outer perimeter of the tile. Once the support has been provided, a first border is provided along a first edge of the tile (step  10 ). Generally, this border is collinear to the support. Once the first border is provided, a second border is provided along a second edge of the tile. This second edge of the tile is substantially orthogonal to the first edge. However, the tile need not be rectangular. Hence, additional variations of this method may provide a second border at some other angle relative to the first border. In order to ensure a secure installation of the tile, one example of alternative method of the present invention provides for maintaining the position of the first border relative to the position of the second border (step  20 ). 
     FIG. 2  is a flow diagram that depicts an exemplary method for maintaining the position of a second border relative to a first border according to the present invention. According to one alternative method, maintaining the position of the first border relative to the second border is accomplished by connecting a first end of the first border to a cross-tie (step  25 ). A first end of the second border is also attached to the cross-tie (step  30 ). Typically, the second border is attached to cross-tie in a manner that renders it orthogonal to the first border. 
     FIG. 3  is a flow diagram that depicts one alternative method for maintaining the position of a second border relative to a first border according to the present invention.
