Added the first set of language independent tests and a Python implementation.

The current tests are just a port of the existing Python tests but I plan to add more.

+This module provides basic functions for parsing mime-type names and matching them against a list of media-ranges.
+
+See section 14.1 of RFC 2616 (the HTTP specification) for a complete explanation.
+
+Testing
+=======
+The Python tests require either Python 2.6 or the installation of the SimpleJSON library.
+
+Installing SimpleJson can be done by:
+sudo easy_install simplejson
+
+Run the tests by typing:
+python mimeparse_test.py

+"""
+Python tests for Mime-Type Parser.
+
+This module loads a json file and converts the tests specified therein to a set
+of PyUnitTestCases. Then it uses PyUnit to run them and report their status.
