A set of simple string distance metrics including:

• Levenshtein edit distance (using http://pypi.python.org/pypi/python-Levenshtein/) (0+)
• Jaro Winkler, Jaro, Ratio distances (0+)
• Title string lengths (0+)
• Uni/bi/trigram distances (0.0-1.0)
• Cosine distance (0.0-1.0)

See test_string_distance_measures.py for usage examples. Each method takes two strings and returns a distance >= 0, some are bounded by 1.0, others aren't.
