Colorimetric data and some data driven colorimetric calculations.
i) Subfolder ColorimetricMatFiles contains .mat files with basic data.

ii) Functions here return various standard data – many routines
take a string argument that allows access to estimates from different

The data routines here are closely coupled to the calculation routines
in PsychColorimetric. The conceptual dividing line between the two folders is
somewhat blurry.
