> In `TreeNode.generateTreeString`, we observed inefficiency in scala collection operations and virtual function call.
> This inefficiency become significant in large plan (we hit a example of more than 1000 nodes). So {*}it’s worth optimizing the super hot code path{*}. By rewriting into native Java code(not so sweet as scala syntax sugar though), we should be able to get rid of most of the overhead.
