Introduced a relaxError when chosing 'r1rho' as experiment type as this won't be implemented now.

Efforts will be concentrated on the CPMG code first, then on the R1rho code.

Rearranged commands in the scripts.

The experiment type and exchange regime will have to be input before the cpmg pulse train delay T.

Corrected capitalisation issues for param names.

These were spotted by Ed in a thread starting at:

Changed the object names so they are lower case as they should be, based on the rest of the code.

Made the equivalent change in the function assemble_param_vector() to allow the system-test to go
further..

Added an 'unresolved' file to the 800 MHz data and moved (and modified) some files (sequence and
readme) so there is only one copy for the 500 and 800 MHz data.

This prevents duplicated files.

Renamed the directories containing the sample datasets provided by Flemming Hansen.

The names are now more obvious as to their content...

This was proposed by Ed in a post at:

The spectrometer frequency in the BMRB is now a float.

Started to dump the relaxation data into the BMRB file.

Much work is still required and the spin specific values are still not there.

Added the relaxation dispersion dataset recorded at 800 MHz in the system-test.

This was kindly provided by Dr Flemming Hansen (flemming AT pound DOT med DOT utoronto DOT ca) and
was previously published in: Hansen, Vallurupalli & Kay, 2008, JPhysChemB, 112: 5898-5904.

The original format was different and two formats were made ('generic' and 'sparky'), as for the
dataset recorded at 500 MHz.

Created a directory for the data recorded at 800 MHz and put a readme file explaining its origin.

The readme file was copied using the command:
svn cp test_suite/shared_data/curve_fitting_disp/dataset_1-a/readme test_suite/shared_data/curve_fitting_disp/dataset_1-b/readme
and was subsequently modified.
