GeometryCollections flattened

[tmcw]

So, possibly a corner-case from Leaflet's perspective, but the hope of geojson.io is that one can do a full cycle through Leaflet and preserve the fidelity of a GeoJSON file.

Test example: http://bl.ocks.org/tmcw/raw/6190994/

GeometryCollections are flattened into their components and output as features. If you output the layer 'above' this, then you get nested FeatureCollections.

Perhaps we should check the type of layer.feature in some cases when converting to GeoJSON.

Yes, there's a number of cases where a round trip loses fidelity -- MultiPoint is one (comes out as a FeatureGroup of Points), I think there may be a couple others.

The second one is with GeometryCollection as described by Tom. I'll take a look at fixing the issue this week.

Both GeometryCollection and MultiPoint should roundtrip now, give it a try guys.
