r18605 - /trunk/specific_fns/n_state_model.py -- March 04, 2013 - 14:02

Author: bugman
Date: Mon Mar  4 14:02:21 2013
New Revision: 18605

URL: http://svn.gna.org/viewcvs/relax?rev=18605&view=rev
Log:
The n_state_model.number_of_states user function no longer requires the 
N-state model to be defined.

This was only needed to update the model information, and is skipped if not 
set.
