The bytecounts.py script produces the formulas that are coded into the
analytical.py script.

The analytical.py script produces the formulas that are coded into the
plotdats.py script.

You shouldn't have to touch either of those, unless the simulator itself
changes.

If you're just plotting the output of simulator logfiles, just do:

$ ./parselogs.py ../path/to/*.log

(the above will generate 5 .dat files)

$ ./plotdats.py

(the above will generate a bunch of .pdf graphs)
