Add support of PostGIS's Azimuth function

[Christian Karrié]

Hi, I would like to see the azimuth function in the gis component.

Thank you very much.

Here is my first try, but it doesn't work:

models.py

class Project(models.Model):
    name = models.CharField(max_length=100)
    center = models.PointField()
    objects = models.GeoManager()

Shell

>>> from karrie.django.ogna.models import Project
>>> mz = Project.objects.get(name="Mainz")
>>> a_dist = Project.objects.distance(mz.center)
>>> a_dist[0].distance
Distance(m=84958.0635775)
>>> a_azimuth = Project.objects.azimuth(mz.center)
>>> a_azimuth[0].azimuth
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/query.py", line 189, in __getitem__
    return list(qs)[0]
IndexError: list index out of range
>>> 

Could somebody point me in the right direction? I plan to implement more spatial functions (mainly PostGIS) into GeoDjango.

I added a patch and a file with some more verbose infos.
