Could it also be used with or merged with multi_array. IOW, a multi_array, m, can be thought of as a tree, where tree depth is m.num_dimensions() and each level of the tree has the same depth and number of children.
I think the interface for a multi_array is different from what one would expect from a tree. So I don't think they should be merged. From what you say, maybe multi_array could use a tree as a backend. Still, if you need indexed access to the nodes, I think you'd be better off with a wrapper around a vector and an index translation scheme than with a tree. Hmm... On second thought, you could probably have a tree view on top of a multi_array or the other way around (I'd go for the first, if I was to choose...) Best, João
