Data union editor model for maintaining information about the edits being
performed. Updates the union to indicate component changes to
the data union. Maintains information about the editor fields (columns)
for a component. Maintains information about the state of the editor:
lock/unlock mode, type of composite (structure/union) , and
whether or not the union has been modified.
It also notifies any registered CompositeEditorModelListener listeners when
the union is changed.
<P>This model provides methods for editing the union and managing how
the changes occur depending on whether or not components are selected and
whether editing in locked or unlocked mode.
Currently unions are only designed to work in unlocked mode.
When edit actions occur and there is a selection, the listener's are notified
of the new selection via the listener's overrideSelection method.
