added the components to implement the half edge data structure:
HEOppAdj : pointer to the opposite half edge HEVAdj : pointer to the vertex HENextAdj : pointer to the next half edge HEPrevAdj : pointe to the previous half edge EFAdj : pointer to the face HEdgeData : groups all previous except (HEPrevAdj)
