revised rmc.f90 and fem.f90 to be  back to their previous version, before i started trying to get the energy to run on a single core and femsim to run on all the rest.
i also fixed my makefile because there was a slight bug where the rmc.f90 object file wasnt being created or wasnt being created with the right stuff or something like that or was being created twice or something like that.

also adding pei's final Zr50 models
