First step in the module design
The new module design allows modules to be registered by adding them
to settings.MODULES. Currently modules cannot do a lot (they can
register with the sidebar and the sitemap), but the structure is in
place.
# Until model subclassing is a possibility, a mixin class is used to add
# the necessary functions that may be contributed for geographic objects.
class GeoMixin:
"""
The Geographic Mixin class provides routines for geographic objects,
however, it is no longer necessary, since all of its previous functions
may now be accessed via the GeometryProxy. This mixin is only provided
for backwards-compatibility purposes, and will be eventually removed
(unless the need arises again).
