 * Description:
 * This class defines an Attr object which is used to look up a method or 
 * other attribute of an object. The Attr object inherits from PyCallable 
 * meaning that this object once created can be called, thus providing the
 * virtual machine with a way of calling methods on objects. In Python, and
 * in the CoCo, the lookup of the method in the object happens when the call
 * occurs (i.e. dynamically).
