The return_spin() and return_spin_from_selection() functions can now handle multiple spins.

It the 'multi' flag is supplied, then lists of spins (and associated data) will be returned, rather
than a RelaxMultiSpinIDError error raised.

Created the list_to_text() RelaxError system function for prettifying the output of RelaxMultiSpinIDError.

Expanded RelaxMultiSpinIDError to be able to print out a list of all the matching spin Ids.

Update and clean up of the model-free LaTeX table generation script.

Improvements for the MoleculeContainer backwards compatibility hook for the creation of proton spins.

The proton element and isotope type is now set to 'H' and '1H' respectively. This now means that
the old XML files require less work by the user to convert to the new interatomic data design.

Conversion of most of the model-free system tests to the interatomic data design.

Eliminated the RelaxProtonTypeError error and changed the RelaxSpinTypeError message.

Bug fix for the dipole_pair.define user function when structural data is missing.
