FIxes issue #301
Now testing if the feature group does not have a feature group type
when checking for same feature instance.
commented out checking for instance with a component type only to
provide warning.
Fixes Issue #299
This is a patch from Philip to deal with serialization and
package sections as named elements not having a name.
commented out two methods that were finding an object closest to a text
location - using LocationInformation from Osate1.
Added getLocationReference as util method to replace the method in
AObject.
removed the two classes as they dealt with OSATE1 style mapping between
text and models.
removed references to AObject.
Still have gotoAObjectMarker and the AObject in the Meta model (Ecore).
changed from IGotoAObject to IGotoModelElement
removed setting of location
Can now correctly parse the BA
Change the location reference methods
