Added ShadingControl model object and initial user script.  Need to add forward and reverse translators.

[#55749402]
Forward translation of shading control only.  We are not yet reverse translating shading materials so I did not do reverse translation of shading controls

[#55749402]
Basing shading control on material rather than construction formulation

[#55749402]
Finally working

[#55749402]
Changing setpoint so blinds are activated

[#55749402]
Minimal GUI access to ShadingControl in plug-in inspector

[#55749402]
Adding script to identify objects that do not need to be moc'd, I agree with Kyle this could save us considerable time (236 extra files to compile in model alone)

[#55749402]
Finishing touches

[#55749402]
Name change

[#55749402]
Adjusting defaults for blinds, shades, and screens to those found in E+ dataset

[#55749402]
Use defaults in forward translators for blind, screen, and shade
