Update on next update.

I've been continuing work on the next update which is planned to include 3D graphics for solutions of the 2D Schrödinger eqn.  Here's a screenshot:

In the above the purplish thing is the wavefunction psi(x,y) and the yellow blobs constitute one of the eigenfunctions of the potential well, which is drawn in transparent light blue. 

I've also got the mouse controls set up so the user can zoom, translate and rotate the 3D graphics in real time.

The next big step will be merging the new code into the Schrödinger lab code.  I think what I'll do is have a separate window for the 2D and 3D graphics, rather than cram everything into one window.
