Added checks for spin specific, analysis API common methods to see if model_info is a SpinContainer.

Converted all of the analysis API base methods into prototype methods.

These all now raise RelaxImplementError when called. All the analyses now alias methods from the
api_common module (which were the original base methods).

Significantly decreased the time required for the frame order mapping system test.

Shifted the path of the new OpenDX frame order mapping system test.

The frame order theory is now using the common _set_param_values_global() analysis API method.

Wrote the arg_check.is_none() testing function.

Created the common method _set_param_values_global() for the analysis API.

Set all col args to None so that there are no automatic defaults.

The automatic defaults make it very difficult for users to debug scripts!!!

Added a system test for the OpenDX space mapping for Euler angle frame order parameters.

Modified the minimisation set() method to better match that of the analysis API.
