Deleted the diffusion tensor parameter setting documentation from the value.set user function.

These values have not been able to be set by the value.set user function for over half a decade.
Therefore this documentation can only lead to user confusion.

More updates of the N-state model sample scripts for the value.set user function changes.

Updated the two_domain.py N-state model sample script.

The value setting for the N-state model is now handled differently.

The N-state model parameter setting documentation has been shifted into the parameter list object.

Deleted the relaxation curve-fitting parameter setting documentation.

This really didn't say anything.

The relaxation dispersion parameter setting documentation has been shifted into the parameter list object.

The documentation has also been rewritten as it originates from Sebastien Morin back in 2009 and is
now very much out of date.

The consistency testing parameter setting documentation has been shifted into the parameter list object.

This has also been updated to reflect the current design of relax.

The J(w) mapping parameter setting documentation has been shifted into the parameter list object.

This has also been updated to reflect the current design of relax.

The model-free parameter setting documentation has been shifted into the parameter list object.

As the text was quite out of date, it has been updated to the current relax design.

Created the parameter list object base class _uf_doc_loop() method.

This will be used to loop over all or subsets of the user function documentation parameter tables.
