quick and dirty XHR helper

get.js

	var get;

	get = function ( url, callback ) {
		var xhr = new XMLHttpRequest();

		xhr.open( 'GET', url );

		xhr.onload = function () {

		xhr.send();
	};

	// export as CommonJS module...
	if ( typeof module !== 'undefined' && module.exports ) {

	}

	// ... or as AMD module...
	else if ( typeof define !== 'undefined' && define.amd ) {
		define( function () { return get; });
	}

	// ... or as browser global
	else {
		global.get = get;
