Import fix for the 'NS 2-site expanded' dispersion model target function.

Updated the dispersion auto-analysis write_results() method for the recent model changes.

Large renaming of the relaxation dispersion models.

This includes both the analytic and numerical models. All of the models with separate R20A and R20B
parameters now have ' full' added to the end of the model name. And all of the corresponding
reduced models whereby R20A = R20B = R20 have had the trailing ' red' removed. All descriptions and
variable names have been updated to match.

Added the 'NS 2-site expanded' model to the relax user manual.

This is the numerical model for the 2-site Bloch-McConnell equations expanded using Maple by Nikolai
Skrynnikov. It originates as optimization function number 5 from the fitting_main_kex.py script
from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see

This commit follows step 2 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Fix for the relax_disp.select_model user function for the 'NS 2-site expanded' model.

There is only one R20 parameter as R20A = R20B in this model.

Added support for the 'NS 2-site expanded' model to the relax_disp.select_model user function back end.

Fix for the lib.dispersion.ns_2site_expanded.r2eff_ns_2site_expanded() function.

The pg variable should have been pA and it needs to be sent into the function.

Added the 'NS 2-site expanded' R2eff calculating function to the relax library.
