Alphabetical ordering of the functions of the specific_analyses.relax_disp.disp_data module.

Shifted out all of the variables and dispersion data specific code into separate modules.

The dispersion data private methods have been converted into functions of the
specific_analyses.relax_disp.disp_data module. The package variables have also been shifted into
the specific_analyses.relax_disp.variables module to avoid circular imports.

Converted the specific_analyses.relax_disp module into its own package.

This is to allow the code to be broken up into separate modules to simplify the analysis.

Started to implement the relaxation dispersion analysis specific calculate() method.

This will be used to calculate the R2eff/R1rho values for the fixed relaxation time period data types
and is equivalent to Sebastien Morin's relax_disp.calc_r2eff user function deleted at r19580
(see http://thread.gmane.org/gmane.science.nmr.relax.scm/17336).

The 2D Grace plots of the exponential curves are now skipped for the fixed relaxation period data types.

This is in the relaxation dispersion auto-analysis.

Fix for the calculation part of the relaxation dispersion auto-analysis.

This is for the fixed relaxation period data types.

The relaxation dispersion class variables for the experiment types are now used for all comparisons.

This should avoid random bugs.

Fix for some RelaxError printouts in the relaxation dispersion specific code.

The Relax_disp.test_hansen_cpmg_data_fast_2site system test now uses the R2eff model.

The equivalent slow exchange system test also uses the model. This model will be used to find the
R2eff values from the fixed relaxation time period data.

The relaxation dispersion scaling matrix assembly now uses lib.mathematics.round_to_next_order().

This allows the printed out I0 values for the optimisation of the exponential curves to be easier
to scale back to the real value.
