124 Change Function Declaration

//FROM
function circum(radius) {...}

//TO
function circumference(radius) {...}

If deprecating something like API code a useful way of accomplishing that easily might be to do something like this:

//FROM
function circum(radius) {
	return Math.PI * 2 * radius;
}

//TO
function circum(radius) {
	console.log("This function is deprecated, please use circumference()");
	return circumference(radius);
}

function circumference(radius) {
	return Math.PI * 2 * radius;
}

This also makes it easy to refactor in place and only change small things like what the contents are of circum() this way if it breaks code we can just handle it in our new function body and all references to circum() are intact until we're able to migrate everything to the new function declaration.
