Shifted all of the user functions to use the auto-generated parameter tables.

All of the specific analysis default_value_doc and return_data_name_doc documentation objects have
been deleted and replaced with the auto-generated ones. This results in a big code clean up and
removes synchronisation issues with the user function documentation quickly becoming out of date
when parameters change.

Shifted the user function documentation creation into the parameter list objects.

The uf_doc() method will now return the pre-created documentation object, and the original base
class method for creating the documentation has been renamed to _uf_param_table().

Fixes for some of the NOE system tests - the NOE parameter description is now different.

Fixes for the specific analysis parameter list singleton object.

These objects are now really singleton objects and are only initialised once.

The default scope for the parameter list object uf_doc() method is now 'spin'.

Most of the parameter tables are for setting spin parameters, so this will minimise code.

Expanded the reduced spectral density mapping parameter descriptions.

Expanded the steady-state NOE parameter description.

The label and caption for the parameter list user function documentation is now supplied to uf_doc().

This allows different types of tables to be generated, for example the default value is useful for
the value.set user function but not value.write, while allowing tables to still be shared.

Spacing fix for one of the diffusion tensor parameter descriptions.

The auto-generated user function tables can now display the base units.
