Solving for potential due to a dipole inside multiple spheres.

The comfile run by this example is as follows:

#Example_c4  Solving for potential in 3 centric spheres due to a centrid dipole

             #This example tests the analytic solution to an centric
             #dipole inside 3 concentric sphere with the solution computed
             #by CMISS.  Note that the potential can be solved for up 
             #to an arbitrary additive constant.
