    /**
     * 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`,

     * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

 **/

/**
 * new MarkdownIt([presetName, options])
 * - presetName (String): optional, `commonmark` / `zero`
 * - options (Object)
 *
 * Creates parser instanse with given config. Can be called without `new`.
 *
 * ##### presetName
 *
 * MarkdownIt provides named presets as a convenience to quickly
 * enable/disable active syntax rules and options for common use cases.
 *
 * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -
 *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
 * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
 *   similar to GFM, used when no preset name given. Enables all available rules,
 *   but still without html, typographer & autolinker.
 * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -
 *   all rules disabled. Useful to quickly setup your config via `.enable()`.
 *   For example, when you need only `bold` and `italic` markup and nothing else.
 *
 * ##### options:
 *
 * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
 *   That's not safe! You may need external sanitizer to protect output from XSS.
 *   It's better to extend features via plugins, instead of enabling HTML.
 * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
 *   (`<br />`). This is needed only for full CommonMark compatibility. In real
 *   world you will need HTML output.
 * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
 * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
 *   Can be useful for external highlighters.
 * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
 * - __typographer__  - `false`. Set `true` to enable [some language-neutral
 *   replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +
 *   quotes beautification (smartquotes).
 * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement
 *   pairs, when typographer enabled and smartquotes on. For example, you can
 *   use `'«»„“'` for Russian, `'„“‚‘'` for German, and
 *   `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp).
 * - __highlight__ - `null`. Highlighter function for fenced code blocks.
 *   Highlighter `function (str, lang)` should return escaped HTML. It can also
 *   return empty string if the source was not changed and should be escaped
 *   externaly. If result starts with <pre... internal wrapper is skipped.
 *
 * ##### Example
 *
 * ```javascript
 * // commonmark mode
 * var md = require('markdown-it')('commonmark');
 *
 * // default mode
 * var md = require('markdown-it')();
 *
 * // enable everything
 * var md = require('markdown-it')({
 *   html: true,
 *   linkify: true,
 *   typographer: true
 * });
 * ```
 *
 * ##### Syntax highlighting
 *
 * ```js
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return hljs.highlight(lang, str, true).value;
 *       } catch (__) {}
 *     }
 *
 *     return ''; // use external default escaping
 *   }
 * });
 * ```
 *
 * Or with full wrapper override (if you need assign class to `<pre>`):
 *
 * ```javascript
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * // Actual default values
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return '<pre class="hljs"><code>' +
 *                hljs.highlight(lang, str, true).value +
 *                '</code></pre>';
 *       } catch (__) {}
 *     }
 *
 *     return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>';
 *   }
 * });
 * ```

// Changes from joyent/node:
//
// 1. No leading slash in paths,
//    e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
//
// 2. Backslashes are not replaced with slashes,
//    so `http:\\example.org\` is treated like a relative path
//
// 3. Trailing colon is treated like a part of the path,
//    i.e. in `http://example.org:foo` pathname is `:foo`
//
// 4. Nothing is URL-encoded in the resulting object,
//    (in joyent/node some chars in auth and paths are encoded)
//
// 5. `url.parse()` does not have `parseQueryString` argument
//
// 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
//    which can be constructed using other parts of the url.

     * @param {String} [popper.content=''] The content of the popper, it can be text, html, or node; if it is not text, set `contentType` to `html` or `node`.
     * @param {String} [popper.contentType='text'] If `html`, the `content` will be parsed as HTML. If `node`, it will be appended as-is.

/**
 * Summary of `ReactBrowserEventEmitter` event handling:
 *
 *  - Top-level delegation is used to trap most native browser events. This
 *    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.

 * - Deactivating events while rearranging the DOM, preventing blurs/focuses,
 *   while guaranteeing that afterwards, the event system is reactivated.
 * - Flushing a queue of collected DOM mutations to the main UI thread after a
 *   reconciliation takes place in a worker thread.
 * - Invoking any collected `componentDidUpdate` callbacks after rendering new
 *   content.
 * - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
 *   to preserve the `scrollTop` (an automatic scroll aware DOM).
 * - (Future use case): Layout calculations before and after DOM updates.
 *
 * Transactional plugin API:
 * - A module that has an `initialize` method that returns any precomputation.
