Overview

TODO:

Graphs could be nicer looking. That is, nodes could be much more easily identifiable, by allowing different classes to tell the node more about itself. A mixin module/protocol should probably be created, just as with the inspector mixin, and added to abstract base and overridden as needed in subclasses. In this way, an object can be more specific about what shape it is, how it is coloured, etc. Reference: http://www.graphviz.org/doc/info/attrs.html

A node in the UI hierarchy. Used by Accessibility::Graph in order to build Graphviz DOT graphs.
