	/**
	 *  The ShippingMethod class defined here contains all the application
	 * context depedant code for the ShippingMethod ORM object.  It represents the
	 * "shipping_method" table in the database, and extends from the code generated
	 * abstract ShippingMethodGen. Additionally it contains data members and functions
	 * to support individual order shipping.
	 *
	 * The actual ShippingRequest object appropriate to the specific method is instantiated
	 * for WebEnabled methods according to the values for this method. If the method has
	 * a class_name field set to "NoClass" a default rate is set (DEFAULT_SHIPPING_CHARGE)
	 * and no Implementation is created (this is a "local pick up" option in the check out ).
	 *
	 * Users of this class should check the flag WebEnabled to determine if the Get*() methods
	 * are of use - GetRate may be called regardless as it will simply return the default rate.
	 *
	 * Basic Usage:
	 *  Get estimate - 
	 *   $objMethod = ShippingMethod::Load($intId);
	 *   $objMethod->Init($objOrder);
	 *   $fltRate = $objMethod->GetRate();
	 *   $strImage = $objMethod->GetLabel();
	 *
	 * @todo - some of the way sizing is dealt with only works for thin things (eg. books, PCBs),
	 *  and multiple packages are not handled. this needs work and perhaps some refactoring of design ..
	 *   
	 * @package Quinta
	 * @subpackage Models
