// Description:
//              This is a helper class to facilate the storage of data that's Critical for set and get.
//              This file is used as a cannister to hold values for Dynamic properties that are
//              not safe to expose and are built to be used only privately.
//              The other caveat is that these dynamic properties should not be needed in the
//              animation or databinding scenarios example: PresenationSource
