typealias ObserverRemover = () -> Void

/*! An observable value
 
 An `Observable` wraps any value. If you add an observer handler, then every time the value is set, your handler will be
 called with the new value. Adding an observer returns a closure that is used to remove the observer. Note that the handler
 is called every time the value is set, even if this does not change the value. If you only want the handler to be called
 when the value changes, see `CoalescingObservable`.

CFRunLoopSource is cool. It lets you build behavior similar to the mechanisms that drive setNeedsLayout and setNeedsDisplay in UIKit.

I found myself in need of something like this a couple of times. It's great to know that no matter how many times I say I need to update something, I will get a single callback at the end of the run loop that gives me a chance to perform my work.

Here is a little Swift wrapper that makes the API easier to deal with.
