starting the FermiONs++ interface, not even close to operational yet
approaching basic functionality in the FermiONs++ interface
Added constraints, fermions interface still unusable
The FermiONs++ interface can produce correct input files
The FermiONs++ interface reports (apparently correct) energies. Geometries not implemented.
fixed a bug in the addition of cartesian constraints for FermiONs++
go fmt'd and deleted some dummy files
Merged fermions, it seems to be working although more tests are needed before merging to master
