The RDC and PCS Q factor user functions now do nothing when data is missing rather than failing.

A warning is given and the function now simply returns rather than crashing.

Fix for the new create_frq_label() function.

Added a new relaxation data function create_frq_label().

This is for generating a frequency label in MHz rounded to the nearest factor of 10.

Fix for the conversion of te to ts - the model is not always given.

The te parameter is now properly converted to ts is the model is one of m5, m6, m7, or m8.

Removed 'relax_disp' from the VALID_TYPES data pipe type array.

This is supported in the 'relax_disp' branch and not in the main line.

The _from_bmrb_model() method can now handle returning the same name.

Alphabetical arrangement of the methods.

Bug fixes for the _from_bmrb_model() and _to_bmrb_model() methods - the model name is now 'name'.

The parameter name is now always defined in _sf_model_free_read() when looping over the params.
