Large renaming of 'structure' to 'molecule' for the structral objects.

Removed the struct_index arg from the Scientific python structral object load_pdb() method.

Removed the struct_index arg from the base api structural object.

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.

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...

The spectrometer frequency in the BMRB is now a float.
