++ Edited row remains highlighted after edit is complete (OK button pressed)
-- Removed unnecessary code
== Changed "data_changed" property to return a boolean isNew value and a corresponding Edited/New Reference Type upon firing so evt.getOldValue() returns the boolean and evt.getNewValue() returns the actual ReferenceType object.
++ Added a method to determine the type of ReferenceType based off of its parent to the ReferenceHelper
