South's fake ORM; lets you not have to write SQL inside migrations.
Roughly emulates the real Django ORM, to a point.

Custom dictionary-like class to be locals();
falls back to lowercase search for items that don't exist
(because we store model names as lowercase).

Creates a Fake Django ORM.
This is actually a memoised constructor; the real class is _FakeORM.

In addition to memoising the ORM call, this function lazily generates them
for a Migration class. Assign the result of this to (for example)
.orm, and as soon as .orm is accessed the ORM will be created.
