 // OSExchangeData
 //  An object that holds interchange data to be sent out to OS services like
 //  clipboard, drag and drop, etc. This object exposes an API that clients can
 //  use to specify raw data and its high level type. This object takes care of
 //  translating that into something the OS can understand.
