/**

 * The Transition component lets you describe a transition from one component
 | 
						|
 * state to another _over time_ with a simple declarative API. Most commonly
 | 
						|
 * it's used to animate the mounting and unmounting of a component, but can also
 | 
						|
 * be used to describe in-place transition states as well.
 | 
						|
 *
 | 
						|
 * ---
 | 
						|
 *
 | 
						|
 * **Note**: `Transition` is a platform-agnostic base component. If you're using
 | 
						|
 * transitions in CSS, you'll probably want to use
 | 
						|
 * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)
 | 
						|
 * instead. It inherits all the features of `Transition`, but contains
 | 
						|
 * additional features necessary to play nice with CSS transitions (hence the
 | 
						|
 * name of the component).
 | 
						|
 *
 | 
						|
 * ---
 | 
						|
 *
 | 
						|
 * By default the `Transition` component does not alter the behavior of the
 | 
						|
 * component it renders, it only tracks "enter" and "exit" states for the
 | 
						|
 * components. It's up to you to give meaning and effect to those states. For
 | 
						|
 * example we can add styles to a component when it enters or exits:
 | 
						|
 *
 | 
						|
 * ```jsx
 | 
						|
 * import { Transition } from 'react-transition-group';
 | 
						|
 *
 | 
						|
 * const duration = 300;
 | 
						|
 *
 | 
						|
 * const defaultStyle = {
 | 
						|
 *   transition: `opacity ${duration}ms ease-in-out`,
 | 
						|
 *   opacity: 0,
 | 
						|
 * }
 | 
						|
 *
 | 
						|
 * const transitionStyles = {
 | 
						|
 *   entering: { opacity: 1 },
 | 
						|
 *   entered:  { opacity: 1 },
 | 
						|
 *   exiting:  { opacity: 0 },
 | 
						|
 *   exited:  { opacity: 0 },
 | 
						|
 * };
 | 
						|
 *
 | 
						|
 * const Fade = ({ in: inProp }) => (
 | 
						|
 *   <Transition in={inProp} timeout={duration}>
 | 
						|
 *     {state => (
 | 
						|
 *       <div style={{
 | 
						|
 *         ...defaultStyle,
 | 
						|
 *         ...transitionStyles[state]
 | 
						|
 *       }}>
 | 
						|
 *         I'm a fade Transition!
 | 
						|
 *       </div>
 | 
						|
 *     )}
 | 
						|
 *   </Transition>
 | 
						|
 * );
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 * There are 4 main states a Transition can be in:
 | 
						|
 *  - `'entering'`
 | 
						|
 *  - `'entered'`
 | 
						|
 *  - `'exiting'`
 | 
						|
 *  - `'exited'`
 | 
						|
 *
 | 
						|
 * Transition state is toggled via the `in` prop. When `true` the component
 | 
						|
 * begins the "Enter" stage. During this stage, the component will shift from
 | 
						|
 * its current transition state, to `'entering'` for the duration of the
 | 
						|
 * transition and then to the `'entered'` stage once it's complete. Let's take
 | 
						|
 * the following example (we'll use the
 | 
						|
 * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):
 | 
						|
 *
 | 
						|
 * ```jsx
 | 
						|
 * function App() {
 | 
						|
 *   const [inProp, setInProp] = useState(false);
 | 
						|
 *   return (
 | 
						|
 *     <div>
 | 
						|
 *       <Transition in={inProp} timeout={500}>
 | 
						|
 *         {state => (
 | 
						|
 *           // ...
 | 
						|
 *         )}
 | 
						|
 *       </Transition>
 | 
						|
 *       <button onClick={() => setInProp(true)}>
 | 
						|
 *         Click to Enter
 | 
						|
 *       </button>
 | 
						|
 *     </div>
 | 
						|
 *   );
 | 
						|
 * }
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 * When the button is clicked the component will shift to the `'entering'` state
 | 
						|
 * and stay there for 500ms (the value of `timeout`) before it finally switches
 | 
						|
 * to `'entered'`.
 | 
						|
 *
 | 
						|
 * When `in` is `false` the same thing happens except the state moves from
 | 
						|
 * `'exiting'` to `'exited'`.
 |
