=== GeoRSS Layers ===
2 methods:
 * Live feed
 * File upload

~~Cache feeds so that if Internet goes down they remain available.~~

Need to replace current implementation using !OpenLayers.Layer.GML
 * !OpenLayers.Layer.Vector with Protocol.HTTP and Strategy.Fixed

Provide a list of pre-populated feeds to select from:
 * http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-M2.5.xml
 * http://volcano.wr.usgs.gov/rss/vhpcaprss.xml

!OpenLayers doesn't yet support different Icons per Category in feed:
 * http://trac.openlayers.org/ticket/1073
