Added search aliases, which work in a similar manner as Django managers.
Test currently fails for this as it seems like __getitem__ of
Bungiesearch appends an additional None item to the list of items. Must
investigate.
Added search aliases, along with tests. tests currently fail when
searching on aliases: for some reason that I have yet to understand, at
this point in the test, there are only two items left in the Article
table (pk'd 1 and 2). I have *no* idea where the third one went,
especially since it exists in the test that creates it. Maybe is it
deleted in the test tear down?
Premeptively bumped to version 0.0.5.
Added post delete signal and test for it. Search alias test now works
correctly as well. It seems like the object created in the test was
deleted by django *without* calling the post delete signal. However,
with the post delete signal and forced call to `.delete()`, the index is
updated correctly and all test succeed.
Added search aliases. Defaults to `bungie_`.
Now in version 0.0.5 .
