The function for sorting global from local parameters in the generic_fns/value.py file has been
simplified thanks to the change of the previous revision whereby the local tm parameter is now
referred to as 'local_tm' rather than 'tm'. Hence no algorithms are required to distinguish
between the global 'tm' parameter and the local 'tm' parameter.
