Moved BinarySearchTree into separate file and made leftrb package where everything moved.

Added leftrb.egg-info/ into .gitignore.
Splitted the search into tree and node methods.
Moved the test into proper package.
Updated version number to 0.1.1, made install require distribute and test require pytest. Updated description as restructured text.
