   *
   * @description
   *   Sanitizes an html string by stripping all potentially dangerous tokens.
   *
   *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
   *   then serialized back to properly escaped html string. This means that no unsafe input can make
   *   it into the returned string.
   *
   *   The whitelist for URL sanitization of attribute values is configured using the functions
   *   `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider
   *   `$compileProvider`}.
   *
   *   The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
   *
   * @param {string} html HTML input.
   * @returns {string} Sanitized HTML.

   * @ngdoc filter
   * @name linky
   * @kind function
   *
   * @description
   * Finds links in text input and turns them into html links. Supports `http/https/ftp/mailto` and
   * plain email address links.
   *
   * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
   *
   * @param {string} text Input text.
   * @param {string} target Window (`_blank|_self|_parent|_top`) or named frame to open links in.
   * @param {object|function(url)} [attributes] Add custom attributes to the link element.
   *
   *    Can be one of:
   *
   *    - `object`: A map of attributes
   *    - `function`: Takes the url as a parameter and returns a map of attributes
   *
   *    If the map of attributes contains a value for `target`, it overrides the value of
   *    the target parameter.
   *
   *
   * @returns {string} Html-linkified and {@link $sanitize sanitized} text.
   *
   * @usage
