Created the Relax_disp.test_hansen_trunc_data GUI test for checking the GUI dispersion auto-analysis.

This checks the full operation of the relaxation dispersion GUI analysis, without checking the final
results (to be added later).

A dispersion saved state from the prompt or script UI can now be associated with a GUI analysis.

Added the results from NESSY of the analysis of Flemming Hansen's truncated CPMG data.

This is only for the truncated data of residues 70 and 71. All files, except for the PNG graphics,
have been added to the repository. The 'summary' file has been created to hold the data from
NESSY's summary tab, as this is not stored in the NESSY saved state and is permanently lost after
closing NESSY.

Created a directory for the results of the CPMGFit program using Hansen's truncated CPMG data.

The script 'cpmgfit.py' has been added to create the input files for CPMGFit and execute the
program. The input and batch files have been added to the repository as well.

Created the Relax_disp.test_hansen_cpmgfit_input system test.

This is for checking the operation of the relax_disp.cpmgfit_input user function conversion of
Flemming Hansen's CPMG R2eff values into input files for CPMGFit. A relax state file containing the
results of an analysis of an 'R2eff' model analysis of the truncated data has been added to the test
suite data to speed up the test and to check the loading of dispersion state files.

Added support for interfacing with Art Palmer's CPMGFit program.

The two new user functions relax_disp.cpmgfit_input and relax_disp.cpmgfit_execute have been created
to interface with CPMGFit. The first creates the per spin system CPMGFit input files as well as a
batch script for executing CPMGFit with all the input files. The second bypasses the batch script
and allows CPMGFit to be executed from within relax. This mimics the palmer and dasha user
functions. The back end code is in the new specific_analyses.relax_disp.cpmgfit module.

Fix for the setup of the relaxation dispersion GUI analysis.

The base method add_execute_relax() has been renamed to add_execute_analysis().

Fixes for the LM63 dispersion CPMG model.

The 'r2' model parameter is now an array as there is one R2 value per magnetic field strength. And
the 'rex' parameter has been renamed to 'phi_ex' and is scaled quadratically with the field strength
within the optimisation target function.

Added a script to the test suite shared data for analysing the truncated Hansen CPMG data.

Speedup for the relaxation dispersion system tests which use Flemming Hansen's CPMG data.

The system test script now reads the truncated data files (of only residues 70 and 71) to minimise
the time required to read the data and store it in the relax data store.
