Now I see - adding findN_AAX_Iter would require ind_210? I suppose it's 
not worth it, as AAX and XAA are not needed in practice, at least not at 
the moment. In Traversals, I should rather modify findComponents to get 
the initial node set as an iterator, so the caller can limit it to its 
needs.

(Graphs.toModel uses XAA, but couldn't the same functionality be 
implemented inside HashGraph without it?)


By the way, a concatenating iterator similar to the one in Traversals 
would be useful in other places as well. At least it allowed me to 
simplify using non-directed properties, combining iterations of 11X and 
X11 into one.

Where to mention this in the docs?
