/**

* @ngdoc service

* @kind function
*
* @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.
