Support simple tree-traversal operations

[aidanmorgan]

Hi,

I've just started playing around with this library, and I'm really impressed. The code is very easy to use and understand,

I was wondering if there would be any way that some simple tree traversal methods could be added? I would love to be able to choose how I would like the tree to be presented (e.g. using graphvis, or a "truth table"), however at the moment I am having difficulty working out exactly how to move through the tree that is generated after training.

I would think that a "simple" getPathToLeaf|Root, [depth|breadth]FirstSearch() etc. would be really helpful.

Also, is there a simple way to work out exactly what should be displayed when looking at a specific cycle through the tree? Sometimes I end up generating paths through the tree that look exactly the same (i.e. they branch on the same values and end up at different leaves).

Cheers,

Aidan
