Multiple shading controls for a single subsurface

[joseph-robertson]

Issue overview

We implemented #4066 to allow a single subsurface to reference multiple shading control objects. While the API now permits this, it appears that the simulation is ignoring any additional shading controls beyond the first one.

Current Behavior

The "Window Control" table in eplustbl.htm does not contain any rows for "Shading Control 2".

Expected Behavior

The "Shading Control 2" object has subsurfaces applied to it, so we'd expect it to be listed in the "Window Control" table.

Steps to Reproduce

Run shadingcontrol_singlezone.rb from OS-resources: https://github.com/NREL/OpenStudio-resources/blob/develop/model/simulationtests/shadingcontrol_singlezone.rb. Look at eplustbl.htm.

Possible Solution

Maybe some specific property(ies) need to be set on "Shading Control 2", otherwise it gets ignored?
