Adds a 'pyplot' interactive command that renders simulated vectors with 

matplotlib -- a Python counterpart to ngspice's 'gnuplot' command. Same
syntax (pyplot <file> <plot expressions...>): the first word is the output file name only when it is NOT a plot expression, the rest are ordinary plot expressions handled by plotit().
