Created the specific analysis API common method _is_spin_param_false().

This simply returns False. The is_spin_param() frame order method has been deleted and this common
method is now used instead.

The specific API PARAMS object is now private.

Apart from fixing a number of unit tests, these aliased singletons should not be accessed by the
rest of relax.

Shifted the frame order specific API deselect() method into the Api_common base class.

The method has been renamed to _deselect_global() and extended to handle Monte Carlo simulations.

Eliminated the specific analysis API object base __init__() method.

This is no longer needed as the parameter list object is now analysis specific and set up by each
analysis type separately. The calls to this method from the derived classes have therefore also
been deleted.

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).
