    /**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array of at least `200` elements
     * and any iteratees accept only one argument. The heuristic for whether a
     * section qualifies for shortcut fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

/**
 * Love them or hate them, `<Modal/>` provides a solid foundation for creating dialogs, lightboxes, or whatever else.
 * The Modal component renders its `children` node in front of a backdrop component.
 *
 * The Modal offers a few helpful features over using just a `<Portal/>` component and some styles:
 *
 * - Manages dialog stacking when one-at-a-time just isn't enough.
 * - Creates a backdrop, for disabling interaction below the modal.
 * - It properly manages focus; moving to the modal content, and keeping it there until the modal is closed.
 * - It disables scrolling of the page content while open.
 * - Adds the appropriate ARIA roles are automatically.
 * - Easily pluggable animations via a `<Transition/>` component.
 *
 * Note that, in the same way the backdrop element prevents users from clicking or interacting
 * with the page content underneath the Modal, Screen readers also need to be signaled to not to
 * interact with page content while the Modal is open. To do this, we use a common technique of applying
 * the `aria-hidden='true'` attribute to the non-Modal elements in the Modal `container`. This means that for
 * a Modal to be truly modal, it should have a `container` that is _outside_ your app's
 * React hierarchy (such as the default: document.body).

 *    may only occur in the main thread and is the responsibility of
 *    ReactEventListener, which is injected and can therefore support pluggable
 *    event sources. This is the only work that occurs in the main thread.
 *
 *  - We normalize and de-duplicate events to account for browser quirks. This
 *    may be done in the worker thread.
 *
 *  - Forward these native events (with the associated top-level type used to
 *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
 *    to extract any synthetic events.
 *
 *  - The `EventPluginHub` will then process each event by annotating them with
 *    "dispatches", a sequence of listeners and IDs that care about that event.
 *
 *  - The `EventPluginHub` then dispatches the events.
