ZapFace() public method

Destroys a face and removes it from the global face list. All edges of fZap will have a NULL pointer as their left face. Any edges which also have a NULL pointer as their right face are deleted entirely (along with any isolated vertices this produces). An entire mesh can be deleted by zapping its faces, one at a time, in any order. Zapped faces cannot be used in further mesh operations!
