||Creates a 2D matrix describing the distance between any two actors in a
single mode-relation pair using a shortest-path measure of distance.
||Class for finding only components that are strongly connected.
||Helper class for performing manipulations of weka Instance and Instances objects.
||Provides link betweeness calculations for algorithms that use it continuosly
rather than once.
||Core abstract class for algorithm cores that utilize shortest-path info
in their algorithms.
