Fixes for the spacing after some equations in the relax_disp.select_model docstring.

Added the 'M61 skew' model to the relax_disp.select_model user function frontend.

This is the Meiboom 1961 model for skewed populations (pA >> pB).

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

Added the 'M61 skew' model to the specific_analyses.relax_disp.variables module.

Updates for the model variable docstrings.

Updated the results of relax's analysis of the truncated CPMG data from Flemming Hansen.

Fixes for the dispersion specific model_statistics() method.

This now handles spin clustering correctly.

Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.

One of the models for one spin now optimises completely and the checks have all been loosened.

Completely redesigned how parameters are handled in the relaxation dispersion analyses.

The key concept is that everything revolves around the new loop_parameter() function. This is a
generator function which loops over the parameters of a given cluster, yielding all the information
required to access the parameter. The other functions of the parameters module use loop_parameter()
to sequentially handle each parameter. This allows for huge simplifications of these functions.

Fixes for the value.write user function for simple parameter values of None.

This is a recently introduced bug which causes a complete failure of the user function is the
parameter for any spin is None.
