Remove stub of omega g usage

[marcpaterno]

Description

Firecrown's support of Omega_g has always been just a stub. It could be set, but then was not used for anything. This commit removes the stub usage.

Any user code that had set Omega_g would have do so with no effect, while perhaps expecting that the provided value actually was used.
