Changed the order of some instructions in the release checklist document.

Changed the version number to 3.2.2.

Updated the CHANGES file for relax 3.2.2.

Added profiling script for testing the lib/dispersion/cr72.py file.

This script creates the relax datastructures, and issues the call to the target function.

It was discussed in:
http://thread.gmane.org/gmane.science.nmr.relax.devel/6022.

Expanded the CaM isotropic cone test data frame_order.py optimisation script and added the results.

The optimisation is now implemented as in the auto-analysis, with an iterative increase in accuracy
of the quasi-random numerical integration together with an decrease of the function tolerance cutoff
for optimisation. The accuracy of the initial chi-squared calculation is now much higher. And the
accuracy of the initial grid search and the Monte Carlo simulations is now much lower.

relax version 3.2.2.

This is a major feature and bugfix release. This includes a large speed up of all analytic
relaxation dispersion models, the correct handling of edge case failures in all models of the
dispersion analysis, and a number of fixes for the handling of list-type data in the GUI user
function windows including the fatal GUI crashes on Mac OS X systems.

Fix for bug #22033, the inability to use other optimisation algorithms in the dispersion analysis.

This is reported at https://gna.org/bugs/?22033. As mentioned in comment #2, the solution is to
raise a RelaxError explaining that only 'simplex' optimisation is possible for the dispersion
analysis as the gradients are not derived and implemented in relax.

Updated the CaM frame order data generation base script to print out more information.

This is for the first axis system so that the same amount of information as the second system is
printed.

Added one more iteration for the zooming optimisation of the frame order auto-analysis.

This is to improve the speed of optimisation when all RDC and PCS data is being used. The previous
iterations where with [100, 1000, 200000] Sobol' integration points and [1e-2, 1e-3, 1e-4] function
tolerances. This has been increased to [100, 1000, 10000, 100000] and [1e-2, 1e-3, 5e-3, 1e-4].
The final number of points has been decreased as that level of accuracy does not appear to be
necessary. These are also only default values that the user can change for themselves.
