 I've refactored the code that was included in the tutorial, which is is more meant as an exercise in helping n00bs dive into figuring out how Apple's code works under the hood, into this library, which I'm hoping will be helpful for anyone dealing with this in production code.

 * If you're using an accessory view via `accessoryType`, that view will automatically be removed and replaced when the cell is opened and closed (respectively). 
 * If you're using a custom background color for your `myContentView` along with an accessory, remember to set that same color as the background color for the cell itself, or the accessory's going to have a different background color.
 * If you're using a cell from a storyboard or a `.xib`, you have to add a `myContentView` view, and hook up the `NSLayoutConstraint` outlets to the left and right constraints. See the sample project for an example of how to set this up.
 * If you're using a cell from a storyboard or a `.xib`, make sure you're sending any calls to the superclass during setup which need `myContentView` to not be `nil` through `awakeFromNib` instead of `initWithCoder:`, since the `IBOutlet` won't be hooked up until `awakeFromNib` has fired.
