Comment fix.

Clean up and fixes for the frame order model_statistics() API method.

The number of data point 'n' was incorrectly calculated using the original alignment tensor base
data.

Docstring fixes for the frame order specific analysis API object.

A number of the methods were referring to the base data as being alignment tensors, but this has
changed to RDCs and PCSs a long time ago.

Clean up of the base_data_types() frame order function and it use.

The propagation of the data type list around the frame order code is now greatly reduced. And the
alignment tensors and NOESY data have been removed from the base_data_types() function - these are
not used.

Simplified the assemble_scaling_matrix() frame order function.

The data_type argument no longer does anything, so has been eliminated.

Removed many unused imports (should have occurred in the previous commit).

Elimination of the specific_analyses.frame_order.checks.check_rdcs() function.

This function duplicates the functionality of pipe_control.rdc.check_rdcs() while not being as
comprehensive. Switching to the pipe_control.rdc version minimises the amount of code in the frame
order analysis, decreasing the potential for bugs.

The frame order analysis is now using the special frame order parameter object.

Simplification of the specific_analyses.frame_order.optimisation.unpack_opt_results() function.

Looping over the cdp.params parameter list is now used to minimise the amount of replicated code.

Clean up of the specific_analyses.frame_order.parameters module.

The unused and terribly designed assemble_limit_arrays() function has been deleted. And unused
imports have been removed.
