gis: Refactor of the GeoQuerySet; new features include:
(1) Creation of internal API that eases generation of GeoQuerySet methods.
(2) GeoQuerySet.distance now returns Distance objects instead of floats.
(3) Added the new GeoQuerySet methods: area, centroid, difference, envelope, intersection, length, make_line, mem_size, num_geom, num_points, perimeter, point_on_surface, scale, svg, sym_difference, translate, union.
(4) The model_att keyword may be used to customize the attribute that GeoQuerySet methods attach output to.
(5) Geographic distance lookups and GeoQuerySet.distance calls now use ST_distance_sphere by default (performance benefits far outweigh small loss in accuracy); ST_distance_spheroid may still be used by specifying an option.
(6) GeoQuerySet methods may now operate accross ForeignKey? relations specified via the field_name keyword (but this does not work on Oracle).
(7) Area now has the same units of measure as Distance.
Backward Incompatibilites:
- The aggregate union method is now known as unionagg.
- The field_name keyword used for GeoQuerySet methods may no longer be specified via positional arguments.
- Distance objects returned instead of floats from GeoQuerySet.distance.
- ST_Distance_sphere used by default for geographic distance calculations.
