/**
 * PushDrawer - stateless drawer that pushes main content to the side when open.
 * Uses render props for drawer header, drawer content and main content.
 * Supports smoth animations for drawers on the left and right side that can
 * be used simultaneously.
 *
 * Example usage:
 *
 * import PushDrawer, { DrawerHeader} from './PushDrawer/PushDrawer';
 * const [isOpen, setIsOpen] = useState(true);
 *
 * <PushDrawer
 *  leftDrawer={
 *    {
 *      content: () => <div> I'm the left drawer content </div>
 *      header: () => <DrawerHeader onClose={() => setIsOpen(false)} title={'My drawer'} />,
 *      isOpen,
 *      width: '100px',
 *    }
 *  }
 *  mainContent={() => <div>I'm the main content</div>}
 * />
