Using gnuplot to create plots.

Now there is a shell file that drives Make to build C binaries that are then compared
using a Perl script that creates CSV files that are then aggregated by another Perl script
that are then plotted using a script that drives gnuplot so you can see the results in
a browser.
Added results .svg file for mergesorts. Results not useful though.

Not sure what is going on, I think when I tested this last time there was an optimal window size of around 32.
Maybe the testing is wrong, or maybe the aggregation? Not sure yet. These are the results as I have them now anyway.
