Implements the null object pattern <http://en.wikipedia.org/wiki/Null_Object_pattern>_.
Provides:
a Null singleton that can be used like None (but is not None and
is not equal to None)
a NullList that returns Null instead of raising IndexError
a NullDict that returns Null instead of raising KeyError
a nullify() routine that converts mappings and sequences to the nullified
variant
an unset singleton for clearing up APIs to distinguish between a keyword
argument that is set by the user as None and simply not set by the user
The easiest way would be to extract the source tarball and run::
$ python test/test_null.py
