Removed all calls to get_time_mem and the function itself from create_hv_mesh.
Factored a function out of main that contains the full fire-test capability as test_hv_cube_mesh. This function will only require the area of the hv region, the valence of the verts in that region, and it will return the fire timing.
Correction to the create_hv_mesh program such that it deletes the mesh in the dag moab instance after testing the mesh. Updats to the Makefile to include the new header file, which was also created btw.
