//---- setup -------------------------------------------------------
// Do NOT make a setup function.
// This is done for you in the API. The API setup just creates a canvas.
// Anything else you want to run at the start should go into the following two 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 -------------------------------------------------------

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