/**

 * @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 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

   <span ng-bind-html="linky_expression | linky"></span>
