// Module pattern
// http://www.adequatelygood.com/JavaScript-Module-Pattern-In-Depth.html
// This is a Immediately Invoked Function Expression (IIFE)
// tho i'll probably call it a self executing anonymous function
// It's used to create a new scope so that 
// we don't muddy up the global namespace building our module
var DataCollector = (function (Twit, _) {
	// Jane is just an internal name for the collector. This fn
	// is the return value of the IIFE.
	var Jane = function () {

	};

	// any variables declared within this closure 
	// are available for use by any other code in the closure
	// (closures are kind of like lets in other languages)
	var private_method = function () {

	};

	// methods on the prototype of a function are available
	// on the object returned by `new Fn()`
	// they are essentially public methods
	Jane.prototype.public_instance_method = function () {

	};

	return Jane;
})(Twit, _);
