Added a link to Troels' post to the relax-devel mailing list to the relax wiki FTP backup script.

Added the script from Troels Linnet for backing up the relax wiki via FTP.

This is from the post http://article.gmane.org/gmane.science.nmr.relax.devel/4168.

Added the 'NS 2-site 3D red' model to the relax_disp.select_model user function frontend.

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

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

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

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

(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

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
http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4159.

Speed ups for the 'NS 2-site 3D' model.

The pi-pulse propagator is created only once upon target function initialisation rather than for
each function call, each spin cluster, each magnetic field strength, each dispersion point, and each
CPMG block.

Converted the pi-pulse propagator matrices to numpy array format.

This is to enable the use of the much faster numpy.dot() function for performing the dot products.

Improvements to the nesting() method of the relaxation dispersion auto-analysis.

The use of the parameters of the simpler model in a nested pair now only works if the simpler model
is in the model list.
