Solvation energy test case.  The canonical electrostatics test case: Born ion.
A non-polarizable ion with a single embedded point charge; has an analytical
solution for the potential.  We examine the solvation free energy as a function
of ionic radius.

The shell script ./runme will generate ions of several radii and calculate the
solvation energies (which will appear in OUTPUT-XXX, where XXX is the
particular radius of interest).  Please see apbs.in for details on the
particular solvation energy calculations.  Analytical results are given in
pmf.dat.

Note:  You may need to edit the path to your Bourne-like shell in the ./runme
script.

Substitute apbs-AUTO.in for apbs.in in the ./runme script to use automatic
focusing.
