[cgma-dev] Seg fault when loading OCC geometry with associations

[Tim Tautges]

To re-iterate, iRel/Lasso currently isn't able to re-associate based on 
the relations saved on tags on the mesh/geometry.  It's necessary to 
create GEOM_DIMENSION sets in the mesh and assign appropriate mesh 
entities to those sets.  This application does show the need to rename 
the association tag to begin with a double underscore, which means it 
doesn't get saved.

Eventually we do need the ability to save and restore the relations tag 
directly, since this will save some time in cases where you're matching 
multiple tags in the infer function.  This is a bit trickier than it 
looks, since the EntityHandle tag type won't make sense across different 
interfaces (i.e. the entity handle for a geom entity can't be saved to a 
file from the mesh interface, since that's just a pointer to the 
RefEntity in CGM, which won't come back the same way).
