No more extendLeaf node in Top-Down construction #41

Closed JinwoongKim closed 8 years ago

JinwoongKim commented 8 years ago

I tried to use extendleaf nodes to save the memory space by storing leaf node information inside extend leaf node, however, the top-down construction make trees have unbalanced degrees.

Currently, I don't use extendleaf node in top-down, which means, leaf nodes remain in memory in a Node form.

Merged with #42
