[BLDG-SIM] Simplied windows and glass libraries

[Ramana Koti]

Kevin,

DOE-2's glass library contains output from LBL's window software. It takes
into account the incident angle dependency of solar heat  gain and visible
light transmittance, which is superior to using the simplified input method.

If you don't find the glazing you want in the DOE-2 glass library, you could
import results from Window software.
