// Base class for bubble controllers. Manages a xib that contains an
// InfoBubbleWindow which contains an InfoBubbleView. Contains code to close
// the bubble window on clicks outside of the window, and the like.
// To use this class:
// 1. Create a new xib that contains a window. Change the window's class to
// InfoBubbleWindow. Give it a child view that autosizes to the window's full
// size, give it class InfoBubbleView. Make the controller the window's
// delegate.
// 2. Create a subclass of BaseBubbleController.
// 3. Change the xib's File Owner to your subclass.
// 4. Hook up the File Owner's |bubble_| to the InfoBubbleView in the xib.

// |anchoredAt| is in screen space. You need to call -showWindow: to make the

// bubble.
// This is the designated initializer.
