Detailed Description

OSOptionalQuantity class to be used in OpenStudio ModelObject properties.

Always contains a Unit. Optionally contains a value. The constructors and assignment operator ensure that this class behaves as "plain old data" (POD) by cloning any units information (to avoid multiple objects pointing to the exact same unit data).
