Rearrangements of the tables in the dispersion chapter of the user manual.

Fixes for the 'MQ NS CPMG 2-site' model equations in the user manual.

Simplified the 'MQ NS CPMG 2-site' model code in lib.dispersion.

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

This is the 2-site numeric solution for multi-quantum CPMG-type data.

This follows the tutorial for adding relaxation dispersion models at:

Added a latex definition for the dwH dispersion parameter and added the 'MQ' abbreviation.

Fixed the 'MQ NS CPMG 2-site' model description in the relax_disp.select_model user function.

The magnitisation vector is 2D, not 3D.
