Converted as_table to be a template tag
This allows us to move all the HTML from python code (which made it
extremely icky and unreadable) to Django templates, which is _a lot_
more readable, and makes it feasable for HTML/CSS experts to change
the way these tables are generated.

# 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).
