Fixed a whole bunch of things to make most of VarGlaS work with FEniCS 1.3+.  Also, simplified sections of the simulations files, to wit the Greenland data assimilation file.  Remember friends, this is publicly available code, and the public repo is not the place for storing your own simulations and addenda to the code.  As yet to do: split the data import steps into two parts, so that the expensive procedure of interpolating data onto the meshes is only done once, after which it just lives as a .xml file.  Also, I need to retest the Greenland transient code (though EISMINT and ISMIP both work in transient right now).  Also, need to fix output of data files.  Right now this is pretty silly and has to be changed inside the code.  What would be great would be a method of directly saving the various objects (Model, Solver, Physics, etc.) for later use.
