I think ill try and contribute some code to this... I have an idea for one and maybe ill try it out and post it. My Idea is for one, it can be vB code or HTML. Then maybe ill create a windows app to have a text box that does it right before your eyes so you can paste or type the code and click a button.
This is a great Idea for a project that everyone could use to make code easier to read on the boards.
