Drive deleted to be renamed for history purposes
Drive renamed to a cpp file
Drive to c++, use git log --follow for history

To expand on above message, drive now uses C++ strings to simply many of
its operations.  The makefile was also slightly modified to deal with the
change.

As for seeing drive's full history, in the command line type:

git log --follow Drive_God_lin.cpp
Changed ValueError except block

Inserted check to detect an error raised by myself.
