Adding Cocoapods support

Hey Aaron,

I found that it would be cool if we could make this project available through [CocoaPods](http://cocoapods.org).

I made the initial changes to make it possible, and it is temporarily working by force-pointing to my fork.

If you want to move forward with this pull request and want to make sure that the public Pod for this project is pointed to your repository, you need to point both the Podspec and the Readme to your repository and submit the Podspec to the public CocoaPods specs repository. (I can help you with that if you need :smile:)

Please, let me know if you don't want to make those changes by declining this pull request, so that I can submit the pointers to my fork.

Thanks!
