added comments
Instantiate now handles opposite correctly for arrays when we have all
to one and one to all.
processing of connection set list in correct order now. From inner to
outer index.
DO the union of connection pattern and connection set, as per standard
9.2.3 (29)
Switched back to checking ending ID incrementally.
Otherwise, when correcting it it stays marked until a save.
Fixes Issue #243

we now maintain the internal lists the same way as specified in tha
standard.
findInstanceObject just has to traverse thing in reverse.
Changed connection instance creator to maintain reference to feature
instance on stacks rather than indices from the feature group.
THis allows for matching by name as well as by index.
Name matching is needed for subset. Index is only used if the enclosing
feature groups have inverse types and both define names - thus they are
redefining names.
Fixed issue with ordering of elements in connection pattern. Needed to
be from inner to outer.
Fixes Issue #245

We were not resolving the upper half of each connection reference.
moved some methods to Aadl2InstanceUitl
getAcrossConnectionReference is now without a context parameter.
