Add tree:

createTree(depth, width, obj) where
- depth is the distance from the root to the farthest node
- width is the number of children to add to each node
- each property/value pair in obj contains a value that will be evaluated to get the final result. The property that contains the array of child nodes should have the value of "__RECURSE__"
