/* __________________________________________________________________________________________________________________
  |  Button.h is the header file for the Button class - which is used to draw octave buttons on the touch screen and |
  |  to check if these buttons have been touched.                                                                    |
  |  It declares data members: caption, color, and the coordinates and dimensions used for drawing the octave        |
  |  buttons.                                                                                                        |
  |  It also declares methods (also known as member functions): draw() and contains().                               |
  |  (The implementation of these methods is defined in Button.cpp.)                                                 |
