Create a pod

I created a `.podspec` file, but it is not valid *yet*. All you need to do though is to create a tag and push it:

```
$ git tag -a 0.1 -m "Tag release 0.1"
$ git push --tags
```

Once you do that, you need to fork [the CocoaPods Specs repository](https://github.com/CocoaPods/Specs), create an `IGIdenticon` directory, and put the `.podspec` file in it. Then just send a pull request and wait.

That is, if you accept to pull in the request :smile:
