Title:         Adding Bi-directional search algorithm to the pgRouting engine

Abstract:      The aim of this project is to enhance the functionality of the 
               current version of pgRouting as part of PostLBS by implementing 
               a bi-directional search algorithm. If time allows, a hierarchical 
               search will be considered as well.
