Coded around an issue where the antenna violation checker comes up 

with zero gate error (and was reporting an infinite antenna ratio).
For now, just ignoring the zero-area case.  However, since the
procedure is supposed to be looping through nets connected to
specific devices in the .ext file, then every entry is supposed to
have non-zero area, so there is some underlying problem here that
needs to be fixed.
