/**
* Finds URL for specified action.
*
* Returns an URL pointing to a combination of controller and action.
*
* ### Usage
*
* - `Router::url('/posts/edit/1');` Returns the string with the base dir prepended.
* This usage does not use reverser routing.
* - `Router::url(array('controller' => 'posts', 'action' => 'edit'));` Returns a URL
* generated through reverse routing.
* - `Router::url('custom-name', array(...));` Returns a URL generated through reverse
* routing. This form allows you to leverage named routes.
*
* There are a few 'special' parameters that can change the final URL string that is generated
*
* - `_base` - Set to false to remove the base path from the generated URL. If your application
* is not in the root directory, this can be used to generate URLs that are 'cake relative'.
* cake relative URLs are required when using requestAction.
* - `_scheme` - Set to create links on different schemes like `webcal` or `ftp`. Defaults
* to the current scheme.
* - `_host` - Set the host to use for the link. Defaults to the current host.
* - `_port` - Set the port if you need to create links on non-standard ports.
* - `_full` - If true output of `Router::fullBaseUrl()` will be prepended to generated URLs.
* - `#` - Allows you to set URL hash fragments.
* - `ssl` - Set to true to convert the generated URL to https, or false to force http.
*
* @param string|array $url Cake-relative URL, like "/products/edit/92" or "/presidents/elect/4"
* or an array specifying any of the following: 'controller', 'action', 'plugin'
* additionally, you can provide routed elements or query string parameters.
* @param bool|array $options If (bool) true, the full base URL will be prepended to the result.
* If an array accepts the following keys. If used with a named route you can provide
* a list of query string parameters.
* @return string Full translated URL with base path.
* @throws \Cake\Error\Exception When the route name is not found
