The new dispersion model profiling master script now includes links to the relax wiki.

The models are no longer presented by name but rather by the relax wiki links for each model (see
http://wiki.nmr-relax.com/Category:Relaxation_dispersion for all these links). This is to improve
the Google rank of the relax wiki, as these links may appear in a number of locations.

Critical fix for the recalculation of tau cpmg, when plotting for numerical models.

The interpolated dispersion points with tau_cpgm was calculated with frq, instead of cmpg_frq.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Created a master profiling script for comparing the speed between different dispersion models.

This is similar to the disp_profile_all.py script except it only operates on a single relax version.
The output is then simply the timings, with statistics, of the calculation time for 100 function
calls for 100 spins (either 10,000 function calls for single spins or 100 function calls for the
cluster of 100 spins).

The output of the script for the current disp_spin_speed branch code has also been added.

Added better epydoc sectioning to the lib.dispersion.ns_cpmg_2site_expanded module docstring.

This is to better separate the original scripts used to document the code evolution.

A very small speed up to the MMQ CR72 dispersion model by minimising repetitive maths operations.

This matches the recent change for the CR72 model (r24353), though the Psi calculation was already
using the fast form. Using the disp_profile_all.py script, the speed ups are:

100 single spins analysis:
MMQ CR72: 4.276+/-0.066 -> 4.230+/-0.089, 1.011x faster.

Cluster of 100 spins analysis:
MMQ CR72: 0.883+/-0.015 -> 0.862+/-0.010, 1.024x faster.

Numpy version 1.6 or higher is now required to be able to run relax.

This follows from the series of messages:

- http://www.mail-archive.com/relax-devel@.../msg06288.html,
- http://www.mail-archive.com/relax-devel@.../msg06289.html,
- http://www.mail-archive.com/relax-devel@.../msg06327.html,
- http://www.mail-archive.com/relax-devel@.../msg06335.html.

If too many users complain, maybe this change can be reverted later. This minimal numpy version is
needed for many of the speed ups going in the relaxation dispersion and frame order analyses. It is
required for the numpy ufunc out arguments and for the numpy.eigsum() function. These will likely
be used in other analyses in the future for improving the speed of relax, so it might affect users
of other analyses later on.

Updated the numpy minimal dependency in the installation chapter of the manual to version 1.6.
........

Removed unused imports.

This is from the splitting of the specific_analyses.frame_order.uf module into the new geometric
module.

Removal of a tonne of unused imports in the lib.dispersion package.

These were identified using the command "pylint * --disable=all --enable=unused-import".

Updated the numpy version requirement to be >= 1.6 on the http://www.nmr-relax.com/download.html webpage.

Updated the numpy minimal dependency in the installation chapter of the manual to version 1.6.
