Extremely simple version control for Matlab code

vcp creates backups of existing m-files for easy backtracking when editing code.

The command
vcp myprogram
entered on the command line, looks for an m-file named 'myprogram.m' on the Matlab search path. If it is found at, say, /home/kevin/matlab/plotting/, then a backup copy named 'myprogram.m.000' will be created in /home/kevin/matlab/plotting/devel/ (if the 'devel' sub-directory does not exist, it will be created). Subsequent calls to
vcp myprogram
will create backups named 'myprogram.m.001', 'myprogram.m.002', etc.

The command
vedit myprogram
would do the same, but would also open the specified program in the Matlab editor.

Works in both Unix and Windows.
