Switch from clojure.zip to using arrays. Thinking of the 'tree' differently may offer some speed improvements.
Initial commit
Using the Tree library (see github) some basic setup and toying
Fixed the confusion in tree-interface.
Working through the migration details ... slowly. Lots of interop to get right.
Fixed get-child and build-tree! is working in simple tests
The tree building is ready for tests to be written. Seems faster than clojure.zip was, but that is to be expected with this much mutation.
