            Reporter: Rashmi Raghu
             Fix For: v1.12


Story

As a MADlib user and developer, I want to implement Breadth First Search / 
Traversal for a graph. BFS is also a core part of the connected components 
graph algorithm.

Accpetance:

1) Interface defined
2) Design doc updated
3) Documentation and on-line help
4) IC and functional tests
5) Scale tests

"Breadth-first search (BFS) is an algorithm for traversing or searching tree or 
graph data structures. It starts at the tree root (or some arbitrary node of a 
graph, sometimes referred to as a 'search key'[1]) and explores the neighbor 
nodes first, before moving to the next level neighbors."
