%description
Provides a function for fast computation of the connected components of an
undirected graph (though not faster than the components() function of the
'igraph' package) from the edges or the adjacency matrix of the graph.
Based on this one, a function to compute the connected components of a
triangle 'rgl' mesh is also provided.
