Doc work

Improved appearance of documentation
It would be so awesome if you would add this to the end of some .rst file where there is a lot of math: 

```
          _,,,_                           _
         /////\\                    _ |\ | \|\  _
        // e e \\                  / `|~\|_/|~\|_) _
       ("   >   ")    _            \_,         |_)|_)
        \\.=-=.//   \/ )     _ |\ /               | \|\
