Rodion Efremov updated SANDBOX-457:
-----------------------------------
Description: A bidirectional Dijkstra's algorithm as described in [these
slides|http://www.cs.princeton.edu/courses/archive/spr06/cos423/Handouts/EPP%20shortest%20path%20algorithms.pdf].
Performed around 10 times faster then unidirectional variant in a supplied
benchmark.
