00017  * DESCRIPTION:
00018  * This is Paul's new Tracker code -- pgrayson@ks.uiuc.edu
00019  *
00020  * A Buttons is a representation for a set of n boolean inputs.  This
00021  * fairly abstract class should be subclassed to make Buttons objects
00022  * that actually know how to get their buttons.  This is somewhat
00023  * parallel to the Tracker object, compare them!
00024  *
