I'm not convinced the fortran code is the file I think it is. This needs furthur investigation.

Modified the python version so that it does no assume that the first coeffient in iota
corresponds to the weight on the LOMO. For systems where core states are used, it is a
waste of time to output and project onto these core states since the weight is always 0.
