//////////////////////////////////////////////////////////
// Instructions for Extension:
// - If you just want to add new elements to the existing game (the current elements being
//   the notes and the speed changes), just extend ScrollElement to create your new one,
//   and add it to the Staff's generateElement function.
// - You could also start completely changing the colour of the game by extending Staff
//   and using completely new scrolling elements.  You will probably be able to keep some
//   of the current Staff functions and override just a few, like generateElement and draw.
// - Look for "HOOK" in the code.  These aren't the only places you can override and change,
//   but will give you a good start.

// NOTE: We're actually hoping you guys get really creative and completely change the game
//       using the same mechanics, just by changing the look and the elements.  We're really
//       curious to see what you'll come up with!
