/**
* @ngdoc service
* @name $sanitize
* @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 a 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 $compileProvider}.
*
* The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
*
* @param {string} html HTML input.
* @returns {string} Sanitized HTML.

* @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.
