void Init ()Initializes 100 rectangles with random colors,
widths between (100-230), heights between (70-150)
and with origin points above the top of the screen.
This function also gives every rectangle a variable
"fall" speed.

void Update (const escher::Stopwatch & stopwatch)On every update tick, update the origin-y component of each
rectangle by its fall speed. If the rectangle reaches the
bottom of the frame, transport it back up to the top of the
frame, with a new random position and color, to give the
illusion of a limitless number of rectangles that continue
to fall endlessly.
