Spinner

I have a simple spinner ui directive I would like to contribute to UI-Bootstrap. It is a numeric spinner (up down). I forked boostrap but I am new to both github, angular and the testing so I was not going to build the tests until I was confident that it was not a waste of time. Please take a look at what I have and let me know if I should pursue finishing the testing and documentation or if this is something someone wants to take on. Thanks.
