Example:

>>> # Create a factory
>>> factory = DataMatrixGraderFactory()
>>>
>>> # Register graders
>>> factory.register_grader("modulation", ModulationGrader)
>>> factory.register_grader("symbol_contrast", SymbolContrastGrader)
>>>
>>> # Get a grader instance
>>> modulation_grader = factory.get_grader("modulation")
