Modelfree4 support fix for the changes to the model-free specific analysis package.

Dasha support fix for the changes to the model-free specific analysis package.

Import fixes for BMRB reading and writing support in the model-free analysis.

Removed the test_grid_ops() method from the specific analysis API.

This has been shifted into the new lib.optimisation module and converted into a function, breaking
a number of circular import kludges.

Shifted some of the specific_analyses.model_free.parameters functions into the new 'model' module.

Shifted the last private method out of the model-free specific analysis API class.

It has been converted into a function of the new 'data' module, for lack of a better name.

Shifted the model-free classic_style_doc user function documentation to the 'uf' module.

Renamed specific_analyses.model_free.results to back_compat.

This is to make the purpose of the module clearer, to avoid developer confusion.

Converted all of the class methods in specific_analyses.model_free.results to functions.

This class has been removed from the API as well.

Updated the model-free specific analysis package __all__ list for the recent changes.
