Fix for a fatal import bug introduced at r20280.

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

This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex
conjugate matrices.

This commit follows step 6 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Added support for the R2B parameter as required by the 'NS 2-site star' model.

This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex
conjugate matrices.

This commit follows step 5 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Created the 'NS 2-site star' model target function.

This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex
conjugate matrices.

This commit follows step 4 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Fix for the non-ASCII character '\xe2' in the lib.dispersion.ns_2site_star module.

Added the 'NS 2-site star' model to the relax_disp.select_model user function frontend.

This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex
conjugate matrices.

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

Updated the lib.dispersion.ns_2site_star module with additional information from Paul Schanda.

The details come from http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4135. The
exchange-free R2 value parameter names have been changed to match the convention of the other
lib.dispersion modules.

Added the lib.dispersion.ns_2site_star module name to the package __all__ list.

Added the 'NS 2-site star' model to the specific_analyses.relax_disp.variables module.

This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex
conjugate matrices.

This commit follows step 1 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Significant speed ups of the lib.dispersion.ns_2site_star.r2eff_ns_2site_star() function.

Replicated calculations have been minimised.
