An example of creating a package

var call_counter = require('./call_counter');

function multiply(x, y) {
	call_counter();
	return x * y;
}

function divide(x, y) {
	call_counter();
	return x/y;
}

function fibo(count) {
	call_counter();
	return private_fibo(count);
}

{
	if(count == 0) return 0;
	if (counter == undefined){
		counter = 1;
		first = 1;
		second = 2;
	}

	result = first + second;
	if(counter == count) return result;
	private_fibo(count, counter, second, result);
	return result;
}
