function Renderer() {

	  /**
	   * Renderer#rules -> Object
	   *
	   * Contains render rules for tokens. Can be updated and extended.
	   *
	   * ##### Example
	   *
	   * ```javascript
	   * var md = require('markdown-it')();
	   *
	   * md.renderer.rules.strong_open  = function () { return '<b>'; };
	   * md.renderer.rules.strong_close = function () { return '</b>'; };
	   *
	   * var result = md.renderInline(...);
	   * ```
	   *
	   * Each rule is called as independed static function with fixed signature:
	   *
	   * ```javascript
	   * function my_token_render(tokens, idx, options, env, renderer) {
	   *   // ...
	   *   return renderedHTML;
	   * }
	   * ```
	   *
	   * See [source code](https://github.com/markdown-it/markdown-it/blob/master/lib/renderer.js)
	   * for more details and examples.

Renderer.renderInline(tokens, options, env) -> String
- tokens (Array): list on block tokens to renter
- options (Object): params of parser instance
- env (Object): additional data from parsed input (references, for example)

The same as [[Renderer.render]], but for single token of `inline` type.
