In this program you will make a flashing explosion wherever you click. STAGE 1 - Create Explosion: Define a helper method that creates an explosion at the coordinates given by parameters x and y. This method should create a circle with radius 0 and give it appropriate properties necessary to make it expand by EXPLOSION RATE every frame until it reaches EXPLTOSION_RADIUS and then contract back to radius 0 at the same rate. STAGE 2 - Mouse Down Method: Define a mouse down method that calls the create explosion helper method passing the mouse x and mouse y coordinates. STAGE 3 - Animate Explosion: Define a timer method that steps each explosion so each circle either increases or decreases by the EXPLOSION_RATE, depending on what stage of the animation it is in. Each circle should also change to a random color each frame, with a red value between 50 and 255, a green value between 0 and 255, and a blue value of 0. When a circle has completed it's explosion (radius has contracted back to O), it should be removed from both the canvas and from the array of explosions.
