[postgis-users] integrated EMPTY GeometryCollections to postgis (in CVS)

[David Blasby]

MULTIPOINT(EMPTY)
MULTILINESTRING(EMPTY)
MULTIPOLYGON(EMPTY)
GEOMETRYCOLLECTION(EMPTY)

These are [almost] fully integrated into PostGIS now.
+ WKT in/out
+ WKB in/out
+ GEOS conversion in/out
+ Indexable
+ collect()

There are a few "weird" cases I need to look at before they're fully 
integrated.

These were added for compliance with the OGC spec.
