Caveat: I am using setFrame:
so these classes probably won't play well with storyboards using Auto Layout at runtime. You should still be able to programmatically add them to a view that has Auto Layout enabled and they should work fine, but loading from a storyboard doesn't set the frames correctly. I welcome any pull requests to fix this since I don't have much experience with Auto Layout.
Please feel free to fork and create a pull request for bug fixes or improvements, being sure to maintain the general coding style and adding comments as necessary.
