Breadth-first search used.
[labels rts] = graph_connected_components(C)
C - connection matrix
labels =[1 1 1 2 2 3 3 ...] lenght(labels)=L, label for each vertex
labels(i) is order number of connected component, i is vertex number
rts - roots, numbers of started vertex in each component, root is some vertex of connected component.

run
zz_test_graph_connected_components_picture.m to test the function, it will find triangle and square separated.
