* Somewhat working version of array nodes
* Fixed bugs related to size changes of the tree
* Check-in the Cargo.lock file
* Update the readme file with a setup note
* Snapshot
* Snapshot #2: rendering leaves
* Snapshot #3: a little bit less duplication
* Using a pseudo unique identifier to triggering changes
* Deduped and simplified cell and leaf node presentation
* Removed branching factor variable
* Drawing links correctly
* Second implementation of size tables
* (snapshot) implementation
