parseTree: (tree: IsTree, callback: forEachCallback) => IsTree

Loop over all the nodes in a tree starting from left and apply a callback for each
parseTreeNext: (treeNode: IsTreeNode, boundaryParent?: IsTreeNode) => IsTreeNode
Be able to parse over every node in a tree.
1. Start at root (get root parent)
2. Get first child (repeat until no children)
3. Check next child
4. Repeat 2
5. Repeat 3
6. If no next child, return to parent and repeat 3
7. Stop at root (next is null and parent is null A boundary can be given to parse only part of a tree: going back up to the parents stops at the boundary, so the parsing stays within the nodes whose parent is the boundary (and everything below them).
