gnuplot can't take filenames as parameters. all
of the scripts expect data.txt as input, and produce plot.ps.
there's a single wrapper "makeplot" that takes the gnuplot file
and applies it to the data file to produce a named postscript plot.

invoke, for example, as:

./makeplot Vel_PWM.gp Vel_PWM.txt plot1.ps

./makeplot FFVel_Unloaded.gp dataLog2.txt plot2.ps

./makeplot FFVel_Loaded.gp dataLog3.txt plot3.ps

./makeplot PVel_VariedGain.gp dataLog4.txt plot4.ps

./makeplot PVel_FixedGain.gp dataLog5.txt plot5.ps

./makeplot DError_Loaded.gp dataLog6.txt plot6.ps
