Improvements for the value.read user function documentation.

The N-state model parameter table has been removed as these parameters are not spin specific and
cannot be read from a file. And the title has been modified.

Improvements for the value.display user function documentation.

The N-state model parameter table has been removed as these parameters are not spin specific and
cannot be used. And the title has been modified.

Updated the value.copy user function documentation for the frame order theory.

The value.copy title has been changed to not be spin specific and a table of the frame order
parameters has been added.

Created parameter tables with no additional trailing text.

This is used in a few of the user functions.

Removed all of the prompt.doc_string.regexp_doc documentation objects from the user functions.

This is the regular expression documentation which no longer has a purpose. It was for specifying
multiple parameters simultaneously in user functions such as value.set, but this functionality has
been removed.

More reordering of the parameter tables for the value user functions.

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The __default_value_doc__ and __set_doc__ documentation objects are out of date and no longer used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.
