KML Filter - filter reports by location (inefficient method)

[Nhorning]

Both NepalMonitor.org and Quakemap.org used a plugin from @himalayantechies called KML filter.

This plugin can use a specially modified KML file to filter (and export with the use of it's sister plugin) reports by location. With Large numbers of reports and/or regions this method becomes inefficient, and is not recommended (we needed an emergency upgrade of the server) but I have placed it here for information, and because of it's state of completion, and because it conceivably be modified to do something else useful.

Instead - it is best to create a database of P-codes (DPA codes in Ecuador) for each report using existing GIS classifications. Please see the relevant issue: #87
