[Geojson] GeometryCollection not treated as a Geometry type

[Stephen Battey]

I've modified my code to handle this change and it all makes sense apart
from an odd naming convention that's occurred in some of my constants.

   GeoJSONSingleGeometry.MULTI_POINT
   GeoJSONSingleGeometry.MULTI_LINE_STRING
   GeoJSONSingleGeometry.MULTI_POLYGON

At first it seemed a little strange to be referring to a multi
point/line/polygon as a 'single' geometry. But, although the names sound
contradictory, a single geometry can be made of multi points or
polygons.

Well, this got me wondering ... if we can define a geometry using a
geometry collection (i.e. multiple geometries), are MultiPoint,
MultiLineString and MultiPolygon redundant?

Feedback welcome. Going to go through the rest of the doc now and see if
it's unclear anywhere else.
