* RESTful cURL class

* // enable cookie
* $c = new curl(array('cookie'=>true));
* // enable proxy
* $c = new curl(array('proxy'=>true));
*
* // HTTP GET Method
* $html = $c->get('http://example.com');
* // HTTP POST Method
* $html = $c->post('http://example.com/', array('q'=>'words', 'name'=>'moodle'));
* // HTTP PUT Method
* $html = $c->put('http://example.com/', array('file'=>'/var/www/test.txt');
