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)
