 * A class that serves as a basic service-container for VELOX.
 * This class has most VELOX classes as public properties:
 * - `$event`: Instance of the `Event` class.

 * - `$router`: Instance of the `Router` class.
 * - `$globals`: Instance of the `Globals` class.

 * - `$misc`: Instance of the `Misc` class.
 *
 * Example:
 * ```

 * $app = new App();
 * // get an instance of the `Router` class via public property access notation
 * $app->router->handle('/dump', 'dd');
 * // or via calling a method with the same name
 * $app->router()->handle('/dump', 'dd');
