adjust library hierarchy
added assumed library types to require_relative tree.
ADL parser should be after Base parser.
bumped to 1.2.10
parent assingment at CAttribute.
changed from each method to inject
fixed injection
removed unused methods
minor revision change. CAttribute has parent.
Simplify code when set parent of children in CAttribute.
Set parent of attributes in CComplexObject in the same way.

So we have back links in constraint tree.
