// uppercased versions).
//
// Here's an example showing how it happens. Lets take greek letter omega:
// uppercase U+0398 (Θ), U+03f4 (ϴ) and lowercase U+03b8 (θ), U+03d1 (ϑ)
//
// Unicode entries:
// 0398;GREEK CAPITAL LETTER THETA;Lu;0;L;;;;;N;;;;03B8;
// 03B8;GREEK SMALL LETTER THETA;Ll;0;L;;;;;N;;;0398;;0398
// 03D1;GREEK THETA SYMBOL;Ll;0;L;<compat> 03B8;;;;N;GREEK SMALL LETTER SCRIPT THETA;;0398;;0398
// 03F4;GREEK CAPITAL THETA SYMBOL;Lu;0;L;<compat> 0398;;;;N;;;;03B8;
//
// Case-insensitive comparison should treat all of them as equivalent.
//
// But .toLowerCase() doesn't change ϑ (it's already lowercase),
// and .toUpperCase() doesn't change ϴ (already uppercase).
//
// Applying first lower then upper case normalizes any character:
// '\u0398\u03f4\u03b8\u03d1'.toLowerCase().toUpperCase() === '\u0398\u0398\u0398\u0398'
//
// Note: this is equivalent to unicode case folding; unicode normalization
// is a different step that is not required here.
//
// Final result should be uppercased, because it's later stored in an object
// (this avoid a conflict with Object.prototype members,
// most notably, `__proto__`)

* // 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!');

**/
/**
* 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

*
* By default understands:
*
* - `http(s)://...` , `ftp://...`, `mailto:...` & `//...` links
* - "fuzzy" links and emails (example.com, foo@bar.com).
*
* `schemas` is an object, where each key/value describes protocol/rule:
*
* - __key__ - link prefix (usually, protocol name with `:` at the end, `skype:`
* for example). `linkify-it` makes shure that prefix is not preceeded with
* alphanumeric char and symbols. Only whitespaces and punctuation allowed.
* - __value__ - rule to check tail after link prefix
* - _String_ - just alias to existing rule
* - _Object_
* - _validate_ - validator function (should return matched length on success),
* or `RegExp`.
* - _normalize_ - optional function to normalize text & url of matched result
* (for example, for @twitter mentions).
*
* `options`:
*
* - __fuzzyLink__ - recognige URL-s without `http(s):` prefix. Default `true`.
* - __fuzzyIP__ - allow IPs in fuzzy links above. Can conflict with some texts
* like version numbers. Default `false`.

// 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.
