Rearranged the parameter table ordering in the value user functions.

The order now better matches that of the chapters of the user manual and is consistent between the
functions.

Shifted the model-free parameter writing documentation to the parameter list object.

Removed no longer used imports from user_function.value.

Deletion of the user function documentation in the pipe_control.diffusion tensor module.

The __default_value_doc__ and __set_doc__ documentation objects are out of date and no longer used
anywhere in relax, so they have been eliminated.

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now very much out of date.
