Detailed Description

An empty weight set class.

This class provides all the interfaces of Weight, while they do nothing at all and the class cost no memory usage. This is primarily to be used in algorithms where weights are irrelevant. Any attempt of using member functions of this class will not result in compile time or runtime errors, but the results might not be what one will be expecting.
