Fixes for dead hyperlinks in the relaxation dispersion chapter of the relax manual.

The B14 model links to http://www.nmr-relax.com/api/3.2/lib.dispersion.b14-module.html were broken
as the B in B14 was capitalised.

Fix for a broken link in the development chapter of the relax manual.

Improvements, fixes and expansion of the redirects at http://www.nmr-relax.com/.

Added a script for testing out the parameter nesting abilities of the frame order auto-analysis.

This script attempts to find the dynamics solution without knowing where the pivot is located.
Hence this will be as in the auto-analysis were this pivot point will be used as the base for all
other models.

Fixes for the parallelised grid search for the frame order analysis.

A chi-squared value check was added to the Frame_order_result_command.run() method to check if the
value is lower than the current when the result is returned to the master. Without this check, each
grid subdivision result will be stored as they are returned rather than storing the results from the
global minimum of the entire grid search.

Parallelised the frame order grid search to run on clusters or multi-core systems via OpenMPI.

This involved the creation of the Frame_order_grid_command class which is the multi-processor
Slave_command for performing the grid search. This was created by duplicating the
Frame_order_minimise_command class and then differentiating both classes.

For the subdivision of the grid search, the new minfx grid.grid_split_array() function is used in
the frame order grid() API method. The grid() method no longer calls the minimise() method but
instead obtains the processor box itself and adds the subdivided grid slaves to the processor. The
relax grid_search user function takes care of the rest.

Updated the minfx version in the release checklist document to 1.0.8.

This version has not been released yet, but it will include important fixes and additions for
constrained parallelised grid searches.

Improvements for the printout at the start of optimisation of the frame order models.

This is in the target_fn_setup() frame order method. All the printouts are now in one place and
they are now better formatted and better controlled.

The frame order linear_constraints() function now returns None if no constraints are present.

This allows the code using this to be simplified with respect to turning off the constraints.

Reverted r24495 as this is rubbish.

The pivot point needs to be initially guessed to centre the grid search for the pivot to a
reasonable 20 Angstrom box in the PDB space.

The command used was:
svn merge -r24495:r24494 .

Changed paths:
M /branches/frame_order_cleanup/specific_analyses/frame_order/parameters.py

Modified the specific_analyses.frame_order.parameters.update_model() function.

The pivot parameters are now set to 0.0 if they do not currently exist. They were previously
excluded from this initialisation, but this is required for the frame order models if the pivot is
not initially fixed at a give location in the PDB space.
