Handling of spatial constraint events is now done by the BoundingBoxPanel (common to WFS filtering and AODAAC).
Removed debugger statement.
Spatial constraint events are now bubbled up from map.
Components should register for events on the map, rather than on the control (less coupling etc).
Aodaac layers now have bbox updated properly.
