Settle on a GeoJSON styling standard

[icetan]

At the moment styles for GeoJSON is defined in the properties attribute of a GeoJSON feature as a dictionary called style. The keys under style are the same as the HTML5 canvas API for styling shapes.

I have had a look at GeoJSON CSS and simplestyle and think something like GeoJSON CSS would be a good standard.

Preferably placing the styles dictionary directly under the feature so not to collide with user defined keys under properties.

Also style inheritance might be something to consider, defining a style property in the parent FeatureCollection would set a default style for it's Feature elements.
