Less terrible name?

Howdy! 

I really like this code, and it (and Pushpin) totally fit a use case for us. However, I'm uncomfortable, both personally and professionally, using a library called PollDance. 

There's such good stuff in here! I did the dreary cut-and-paste work of updating the name in the files. If you'd be kind enough to change the repo name too, that would also be awesome.
