// Defines a protocol that allows controllers to delegate resizing their views
// to their parents.  When a controller needs to change a view's height, rather
// than resizing it directly, it sends a message to its parent asking the parent
// to perform the resize.  This allows the parent to do any re-layout that may
// become necessary due to the resize.

// delegates can implement this method if they need to modify their behavior
// while an animation is running.
