Verifying GLIMMER with exact solutions

The tests used here are based on the exact solutions for isothermal ice sheets by Ed Bueler and others. Their tests are coded in matlab and can be found on their web page.

Tests B, C and D are run with the linear and non-linear solver. The ADI solver is not used here.
