* Setup access for origin and methods on cross origin requests

* This method allow multiple ways to setup the domains, see the examples
*
* ### Full URI
* e.g `cors($request, 'http://www.cakephp.org');`
*
* ### URI with wildcard
* e.g `cors($request, 'http://*.cakephp.org');`
*
* ### Ignoring the requested protocol
* e.g `cors($request, 'www.cakephp.org');`
*
* ### Any URI
* e.g `cors($request, '*');`
*
* ### Whitelist of URIs
* e.g `cors($request, array('http://www.cakephp.org', '*.google.com', 'https://myproject.github.io'));`
