	 * This module only contains polyfills; it's not a class.

	 * It's a way to use some polyfills if some features are not available for all browser.
	 * Actually, it contain only one polyfill:
	 *
	 *  - `Function.bind`
	 *
	 *    Mozilla implementation of the bind function.
	 *    See the documentation
	 *    [on the MDN](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Function/bind).
	 *
	 * **Usage example:**
	 *
	 *     define(['TW/Utils/Polyfills'], function() {
	 *         //Now i'm sure that `bind()` exist.
	 *         setTimeout(myFunc.bind(), 100);
	 *     });
	 *
	 * **Note: the module don't return anything.**
