Created the 'NS 2-site 3D red' model target function.

This is the 'NS 2-site 3D' model with R20A = R20B = R20.

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

Converted the Citations chapter of the relax user manual into a preface chapter.

Added the 'NS 2-site 3D red' model to the specific_analyses.relax_disp.variables module.

More changes to the numerical solution dispersion code to match relax's conventions.

This includes the changes of df->dw, fA->wA, fB->wB, and Mgx->Mx.

Speed up for the lib.dispersion.ns_matrices.rcpmg_3d() function.

The pA and pB parameters are now sent into the function rather than being recreated by the function.

Modified the df, fA, and fB parameters to match the relax omega conventions of dw, wA, and wB.

This follows from Paul Schanda's confirmation at
