A Service is a frontend format for FeatureServer. Services parse requests --
including POST/PUT data, GET data via URL parameters and path_info, etc.

Currently included in FeatureServer are four Services:

 * JSON
   The default Service. Input and output is GeoJSON.
   Requires simplejson Python module.

 * GeoJSON 
   Spec-following of GeoJSON. To be merged with JSON eventually. 
 
 * GeoRSS Atom (Simple)

 * KML
 
 * GML/WFS
   This service is output only.

Datasource properties which affect layers:
 * adding 'gaping_security_hole=yes' to any datasource will allow it to be
   loaded via JSON callbacks. You should only enable this option if the data
   you are serving should have unlimited distribution. Enabling this option
   can allow users to obtain data from your server *even if you are behind
   a firewall*. Again, you should only enable this option if the data you
   are working with has *unlimited distribution*. 
   
   Once you do this, simply specify 'callback=' as a parameter, and the
   JSON data will be wrapped inside the following:
     
     callback_value({'data':'here'})

 * title_property will cause KML/GeoRSS to use the valu you set it to as a key
   for the property which fills the <title> property of the feeds.
