Get your Python 3000 geometries on

Python 3.0 is final and I've pushed my port of Shapely to GitHub: http://github.com/sgillies/shapely-3k/tree/master.

The Shapely tests depend quite heavily on Numpy, and are somewhat broken in the new project, but it seems to work:

sean@lenny:~/code/shapely-3k$ python3.0
Python 3.0 (r30:67503, Dec  4 2008, 12:17:44)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> from shapely.geometry import Point
>>> r = Point(0.0, 0.0).buffer(10.0).exterior
>>> r.geom_type
'LinearRing'
>>> r.length
62.806623139095088
>>> import binascii
>>> binascii.hexlify(r.wkb)
b'01020000004200000000...'

It's strings vs bytes now in Python 3.0, which is better, but demands the change in Shapely idiom shown above.
