std::unique_ptr< gis::Geometrycollection >	gis::narrowest_multigeometry (std::unique_ptr< gis::Geometrycollection > geometrycollection)
	Narrows down a geometrycollection to return a Multipoint, Multilinestring or a Multipolygon if the first level of the geometrycollection contains only points, linestrings or polygons. More...
