Definition List Extension for Python-Markdown
=============================================
Added parsing of Definition Lists to Python-Markdown.
A simple example:
Apple
: Pomaceous fruit of plants of the genus Malus in
the family Rosaceae.
: An american computer company.
Orange
: The fruit of an evergreen tree of the genus Citrus.
