org.das2.event.BoxSelectionEvent

This is the range analog to the DataPointSelectionEvent. The DataPointSelectionEvent is a point, and this is a box. Note that it's acceptable to have null xrange and yrange, so that the same code can support a variety of applications. It's left to the programmer to see that these are used consistently.

BoxSelectionEvent( Object source, DatumRange xrange, DatumRange yrange )

create the BoxSelectionEvent with additional planes of data.

BoxSelectionEvent( Object source, DatumRange xrange, DatumRange yrange, java.util.HashMap planes )

create the BoxSelectionEvent with additional planes of data.
