Continuing on modifying Mesh

I'm done for the night. Mainly because my laptop screen is extremely
screwed and won't return to normal. Any further attempts to work will
probably cause me seisure because my screen is flickering and its painful.

I still need to edit functions in Mesh.cpp in order to remove winged edge
functionality. I also need to modify the some functions in WingedEdgeMesh
to accomodiate new signatures.
