//---- setup -------------------------------------------------------
// Do NOT create a setup function 
// But you can create these functions.

function beforesetup()        // Optional
{
    // Anything you want to run at the start BEFORE the canvas is created 
}

function aftersetup()         // Optional
{
    // Anything you want to run at the start AFTER the canvas is created 	
}



//---- draw -------------------------------------------------------
// draw() is not needed. 
// Can use nextStep() or takeAction() instead.

function draw()               // Optional
{
	// can put P5 instructions to be executed every step here, or in nextStep()  
}
