Compliant: added constraint stabilization

DAG: new implemention to correctly maintain the descendancy list. There could be inconsistencies with previous implementation and MultiNodes (like removing only one parent of a multinode should not remove the multinode from the ancestor descendancy, etc.).

The descendancy lists are not longer updated at each graph structure modification, but only (kind of) flagged as dirty. The descendancy is computed from scratch only when you need to use it and it is not up-to-date.

Removing bgl simulation graph that is no longer useful (dag MUST be employed for multimappings).

Simplified CollisionGroupManager. Now there is only one DefaultCollisionGroupManager that works for both tree and dag (and that could work for any other simulation graphs without having to add code in modules-component)
