Manual LinkedList bugfixing; still no lettuce support.
Manual LinkedList troubleshooting: it now appears to be working to spec, minus a print function.
Added write() function to LinkedList (print is a keyword; can't name a funtion that).
Got lettuce tests working: regex special character \w is different in Python than in Perl, apparently.
The final lettuce commit. Many lettuce tests were sketched out, and it's just too damn much. I am switching to unittest to test the LinkedList.
Wrote initial unit tests, got all working for insert function.
Added skeleton classes to unit test file representing all tests that should be run.
Completely fleshed out unit test skeleton file with all tests that should be implemented.
Implented pop tests and fixed a small error in LinkedList's pop function that was revealed by said tests.
Implemented size tests.
Implemented search tests.
Implemented __str__ tests.
Implemented remove tests. All tests are now implemented, and all pass.
Removed if __name__ == '__main__' block from linked_list.py.
