Corner Radius issues

[jimbojsb]

My goal is to make a "square" segmented control. It seems like cornerRadius affects the corner radius of the control, but regardless what value I set that to, the selectedSegmentIndicator maintains a 4.0f corner radius. I see in the code where that is set but I don't see way to adjust it. Based on that, I also don't get how the examples are possible...

After more fiddling, I see that -sizeToFit is what's required to make what I was expecting happen. Not sure if that is expected behavior, but if it is, feel free to close this issue.

The cornerRadius of the NYSegmentedControl is forwarded to selectedSegmentIndicator. That is what makes the examples possible.

I think as for right now the expected behaviour is to call sizeToFit, as it is done in the examples, however there is a PR that changes this need. #20
