[#48742609] OpenStudio.idd added lowtemperatureradiant variable and constant flow zoneHVAC and heating and cooling coils.
[#48742609] corrections and order revisions on OpenStudio.idd on added coil objects.
[#48742609] added ZoneHVAC:LowTemperatureRadiant:Electric and ZoneHVAC:LowTemperatureRadiant:SurfaceGroup to Open Studio idd
[#48742609] Reviewed the Radiant Slab IDD changes.  Made a few changes.  Used SVN to look at changes; let me know if you have any questions.

OS:ZoneHVAC:LowTemperatureRadiant:Electric
OS:ZoneHVAC:LowTemperatureRadiant:ConstantFlow
OS:ZoneHVAC:LowTemperatureRadiant:VariableFlow
    made \field Availability Schedule Name required
  
    removed \field Zone Name - it's zone will be determined by the zonehvacequipment list it is on
    and since we are using surfacegroups only, the only valid choice for this field is the one that all the surfaces
    in the referenced surface group are in
   
    changed \field Surface Name or Radiant Surface Group Name to \field Radiant Surface Group Name becuse we are only allowing these to hook to Surface Groups

    removed surfaces and subsurfaces from the RadGroupAndSurfNames reference list (because we are only allowing these objects to hook to surfacegroups
  
ZoneHVAC:LowTemperatureRadiant:SurfaceGroup  
  changed \reference RadGroupAndSurfNames to \reference RadSurfGroupNames because surfaces are no longer being referenced

[#48742609] lowtemperatureradiant:surfacegroup Openstudio.idd field revision to get rid of build errors. Currently allows two surfaces (floor and ceiling) only without extensible fields.
[#48742609] deleted object lowtemperatureradiant:surfacegroup in OpenStudio.idd, changed lowtemperatureradiant reference field to ceilings and floors keys per discussion with Andrew and Dan.

[#48742609] Another fix on InspectorView.cpp file
[#48742609] Fixes and revi
[#48742609] Fixes and revisions, adding icons.
[#48742609] ConstructionWithInternalSource Code update.
Fixing build error in ruby bindings, also adding extra logic in reverseConstructionWithInternalSource

[#48742609]
Attempting to clean up the ConstructionWithInternalSource interface and adding unit tests to make sure functionality is working

Changed Construction and ConstructionWithInternalSource to throw if passed in empty list of layers rather than segfault

Added defaults to idd, with the way that gui elements are bolted on to attributes using the quantity classes this was the best option, sorry
