Added functionality to compute magnetic force for systems with discontinuous permeabilities.
Added hollow sphere levitation example (computes force on outer and inner surface).

FYI, some results on hollow sphere case. By changing -ref (refinement levels) we getting the following:

ref outer-integral inner-integral
0 359.0276 -0.002127189
1 373.2145 -0.0022614011

analytical outer surface integral is 372.88 N. Analytical inner surface integral is 0 N. So we have pretty good agreement.

I can test higher refinement levels if you want. I just ran these on my laptop for convenience.
