Polygon and linestring support in CDB_WeightedMean #79

CDB_WeightedMean only understand points (due to ST_X/ST_Y) right now.

The most straight forward way I can see to support polygons and linestrings is to use ST_Centroid which gets the center of mass of the geometries, and then use the ST_X/ST_Y as normal

Hey @rochoa do we have a good usecase for lines or polygons?
