 @class InfoBubbleView;
 
 // 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.

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