I think I fixed a bug in the equipotential portion of my plotting
algorithm. Before, the lines in blue did not really show off
symmetry. It erroneously plotted more lines per point and
at different starting radiuses. This attached plot looks like
the equipotentials in blue are fixed...


Here is some further context on the issue:

https://groups.google.com/forum/#!searchin/sci.math/thomasson/sci.math/QMOKhb3xwWg/pwXELKGU8GUJ

Where a James Waldby found, and reported the problem
with the symmetry.


Here is a rendering of the corrected equipotential field:

I added a new control where a user can set the starting
radius for the equipotential field. The problem with the
bugged code was that I was starting equip-field lines at
different radiuses for each point!
