xSupportComponent handeling
With new tools that we have instead of deriving from AOMD::mAttachableData use of DATAMANAGER concept would be more handy.
It would simplify issue #54 by having xcut::xPhysdomain (and others xcut class) providing directly a DATAMANAGER instance.
The getSupportComponnet may remains.
It may remove AOMD specific attachable mechanism in xFEM
