Add ability to select a geographic region from the map for addition to the query constraints #13

Open GoogleCodeExporter opened 9 years ago

Using either an OpenLayers polygon drawing widget or a Shift-mouse-click & drag 
operation get a geographic region and apply it to the query constraint. The 
text format for the geometric representation should be simple such that it is 
easily edited in a request URL.

ArcGIS online 9.3 describes a format that is a good candidate:

And OpenLayers presents options for various vector formats:

GeoDjango supports all of the OGC spatial lookups so actually performing the 
geospatial query should be straight-forward once the UI "plumbing" is in place:
