Add Reference writing to FFWriter in gromacs_writer. Feasible solution:
Add Dictionary with references either {number: Ref} or {ID: Ref} as attribute (no getter setter needed as no one is using it anyway). Then do another arg or kwarg in the add_atomtype, add_crossint dicts and update the writing methods.
For the header do a function writing out all the references and other header information.
