Allow access to AdditionalProperties

Enhancement Request

Allow users to set AdditionalProperties for objects

Detailed Description

AdditionalProperties are used for adding data to objects that can be used in downstream measures. Currently there is no way to see these properties in the UI

Possible Implementation

Allow users to set AdditionalProperties for object in the InspectorGadget so it can be used in OpenStudio Application and SketchUp Plug-in
