inherits from Annotation; inherits from HasButtonInTitleBar;
When the user touches a sticky note, the note zooms open to reveal a window filled with the note's contents. This window is a member of class Annotation. In Magic Cap 1.5, the annotation is an object of class ErasableAnnotation, a subclass of Annotation. If the erasable annotation contains scribbles, Magic Cap puts an erase button in the title bar. The erase button goes away if there are no scribbles in the annotation.
