Fixed showing the correct list of projects for taking a Grading Project Survey.
Note that when a user is a mentor for a lot of Organizations the amount of subqueries might exceed the allowed amount. A TODO has been added to fix this issue. However this will hopefully not be a problem that pops up soon.
Also some minor docstring addition to Project Survey view.
from django.conf.urls.defaults import *
urlpatterns = patterns('',
(r'^$', 'examples.views.index'),
(r'^hello/', include('examples.hello.urls')),
)
