Object.create() polyfill since IE8 doesn't support the create() method.

create_polyfill.js

/**
*   Polyfill for Object.create()
*   use this to create new objects
*/
if (!Object.create) {
	Object.create = function (o) {
		if (arguments.length > 1) {
			throw new Error('Sorry the polyfill Object.create only accepts the first parameter.');
		}
		function F() {}
		F.prototype = o;
		return new F();
	};
}
