It would be good to use the name_ of this propagator in forming the names of all the parameters, in case we have more than one K-matrix instance in a fit (e.g. for pipi and Kpi S-wave in B -> Kpipi).
This comment applies also to lines 455, 502, 530, 536, 542, 548, 554

These parameters have not been given names - should probably be done as per line 463
