- Fixed some bugs in the trace code - Fixed FeatureStruct.deepcopy() to work with cyclic structures - Added FeatureStruct.reentrances() (returns a list of all reentrant   feature paths) - Added more test cases for cyclic structures - Fixed minor bug in demo - Reenabeled demo for script-call (__name__==__main__)
