+ * class MarkdownIt

+ * Main parser/renderer class.
+ *
+ * ##### Usage
+ *
+ * ```javascript
+ * // node.js, "classic" way:
+ * var MarkdownIt = require('markdown-it'),
+ *     md = new MarkdownIt();
+ * var result = md.render('# markdown-it rulezz!');
+ *
+ * // node.js, the same, but with sugar:
+ * var md = require('markdown-it')();
+ * var result = md.render('# markdown-it rulezz!');
+ *
+ * // browser without AMD, added to "window" on script load
+ * // Note, there are no dash.
+ * var md = window.markdownit();
+ * var result = md.render('# markdown-it rulezz!');
+ * ```
+ *
+ * Single line rendering, without paragraph wrap:
+ *
+ * ```javascript
+ * var md = require('markdown-it')();
+ * var result = md.renderInline('__markdown-it__ rulezz!');
+ * ```
+ **/
+
+/**
+ * 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.mjs) -
+ *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
+ * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.mjs) -
+ *   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.mjs) -
+ *   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.mjs) +
+ *   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(str, { language: lang, ignoreIllegals: true }).value;
+ *       } catch (__) {}
+ *     }
+ *
+ *     return ''; // use external default escaping
+ *   }
+ * });
+ * ```
+ *
+ * Or with full wrapper override (if you need assign class to `<pre>` or `<code>`):
+ *
+ * ```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><code class="hljs">' +
+ *                hljs.highlight(str, { language: lang, ignoreIllegals: true }).value +
+ *                '</code></pre>';
+ *       } catch (__) {}
+ *     }
+ *
+ *     return '<pre><code class="hljs">' + md.utils.escapeHtml(str) + '</code></pre>';
+ *   }
+ * });
+ * ```
