/**
 * Modal is a lower-level construct that is leveraged by the following components:
 *
 * - [Dialog](/material-ui/api/dialog/)
 * - [Drawer](/material-ui/api/drawer/)
 * - [Menu](/material-ui/api/menu/)
 * - [Popover](/material-ui/api/popover/)
 *
 * If you are creating a modal dialog, you probably want to use the [Dialog](/material-ui/api/dialog/) component
 * rather than directly using Modal.
 *
 * This component shares many concepts with [react-overlays](https://react-bootstrap.github.io/react-overlays/#modals).
