// Retains "this" attribute as target, and overrides native addEventListener.
target.addEventListener(type, listener, useCapture);

// Has less function calls then the override version, while retains similar formatting.

// Same as the previous, but (arguably) cleaner looking code.

// NOTE: These two features are on by default (so it's easy to add to a project)

----------------------------------------------------

The latest version of MIDI.js makes calls to midijs instead of Event. This fixes issues
with using the library with other frameworks, also, using the Event namespace was a bit hacky.
If you want to use the latest library, but not update your calls (or prefer the Event namespace), 
add this to the bottom of the Event.min.js
///
var addEvent = eventjs.add;
var removeEvent = eventjs.remove;
///
(function() {
	for (var key in eventjs) {
		Event[key] = eventjs[key];
	}
	for (var key in eventjs.proxy) {
		addEvent[key] = eventjs.proxy[key];
	}
})();
