+                   A category on NSObject that allows you observe a
+                   keypath passing in a block to execute when the keypath
+                   changes instead of using a callback method.
+
+                   This works on iOS and OS X.
+
+                   Why? Blocks are funky. They let you define an action at the
+                   same time as you are setting up a observation. In most cases
+                   this leads to clearer code than using a callback.
