Optimal Colour Stimuli
======================
Defines *MacAdam* optimal colour stimuli for various illuminants in *CIE xyY*
colourspace.
The optimal colour stimuli data is in the form of a *dict* of
*tuple* as follows::
{'name': tuple, ..., 'name': tuple}
where each *tuple* contains a collection of optimal colour stimulus *tuple* as
follows::
(('x', 'y', 'Y'), ..., ('x', 'y', 'Y'))
