Hi guys,

finally found a little time to finish hacking together the stab region plotter.

This makes it pretty easy to make comparisons between methods, such as this one between RK4, LSERK, and AB3 (scaled by a factor of 5 to be comparable work-wise with LSERK):

(Note: These are approximate!)

@mattwala @cory Better plot: simply normalized by the number of RHS calls.

So the upshot is that along the imaginary axis, they all deliver about equal progress per RHS call, whereas for for negative real (i.e. diffusion-like) RHSs, there are considerable differences.
