Frank McQuillan commented on MADLIB-1072:
-----------------------------------------

This JIRA is for a basic first implementation:  Later we could look at adding 
more parameters to (optionally) keep run-time/memory tractable:

* limit the number of target nodes
* limit max distance between source and destination
* switch for directed/undirected
* incremental algos for APSP on sub-graph that has been changed/affected 
compared to previous graph state
* approximate techniques

> Graph - all pairs shortest path
