// A connected component algorithm for the case when dynamically
// adding (but not removing) edges is common.  The
// incremental_components() function is a preparing operation. Call
// same_component to check whether two vertices are in the same
// component, or use disjoint_set::find_set to determine the
// representative for a vertex.

// This version of connected components does not require a full
// Graph. Instead, it just needs an edge list, where the vertices of
// each edge need to be of integer type. The edges are assumed to
// be undirected. The other difference is that the result is stored in
// a container, instead of just a decorator.  The container should be
// empty before the algorithm is called. It will grow during the
// course of the algorithm. The container must be a model of
// BackInsertionSequence and RandomAccessContainer
// (std::vector is a good choice). After running the algorithm the
// index container will map each vertex to the representative
// vertex of the component to which it belongs.
//
// Adapted from an implementation by Alex Stepanov. The disjoint
// sets data structure is from Tarjan's "Data Structures and Network
// Algorithms", and the application to connected components is
// similar to the algorithm described in Ch. 22 of "Intro to
// Algorithms" by Cormen, et. all.
