[ImportError] Circular dependencies in __init__ EReference eType initialization

[cgava]

pyecoregen generates initializations of EReference.eType and EReference.eOpposite inside the init.py of each subpackage, which requires a lot of import from other packages, and increase the amount of circular dependencies.

Solution proposed : do those initializations only in the top pyEcoreCapella.init.py module

Implementation:

• generate all those initializations in an intermediate file (called cross_init.inc) in each package submodule
• at top level, create a init.inc with the import statements for each packages
• at top level, create init.py by concatenation of top init.inc and the cross_init.inc of all the packages

attached is the templates (rename txt to tpl in pyecoregen) and the patch for ecore.py
