Fixed logic in felix_driver.cpp such that final solution from a time step is used
as the initial guess for the next time step if the mesh hasn't changed.  This sped
up a 10 yr evolving dome simulation by >35%.

Also moved CismSTKMeshStruct to FELIX/interface_with_cism directory, to emulate mpas_interface
and since this is a better home for it.
