[Radiance-general] CIE version in gensky

[Thomas Bleicher]

Zack Rogers developed a module for Python (IES_gensky.py) that is part of
SPOT and updates the gensky model.

I also seem to remember that in one of the early Radiance workshops there
was a reference to an updated CIE sky generator that could produce all 15
standard sky models. I don't think it ever got a public release but the
source files were exchenged off-list now and then.

Regards,
Thomas
