1. DBSE has been improved (based on the review):
-- Remove functionality of controllers has been improved to also remove its descendants and tests were also added for that .
-- Tests were added for move_up, move_down and reorder functions of the controllers.
-- Some of the long methods in classes were split into small methods.
2. Code was cleaned up and documented.
Improve documentation, scrub code and add more tests wherever required.
Any comments/suggestions are welcomed. The project action plan can be found here http://docs.limesurvey.org/Rebuild+the+database+frontend+using+CodeIgniter
