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.

Fixes for the value.set() back-end to match the analysis API arg changes.

The param and value args should be lists.

Created the set_param_values() API method for model-free analysis.

Created the set_param_values() API method for the N-state model.

Analysis API fixes.

The param_names() and param_values() methods are now called get_param_names() and
get_param_values().

Modified the analysis API common method _set_param_values_spin() to accepts lists as args.
