	Description:

		Adds support for PUT verb in CodeIgniter; populates PHP's $_POST data
		super global with data for PUT requests.


	How to Use:

		Add the following to your 'application/config/hooks.php' file:

			$hook['pre_controller'][] = array(
				'class'    => 'ExtendHttpSupport',
				'function' => 'pre_controller',
				'filename' => 'ExtendHttpSupport.php',
				'filepath' => 'hooks',
				'params'   => array()
			);

		Also, make sure hooks are enabled in your 'application/config/config.php' file.
