    Test the named class.

    Some classes will generate a TypeError or an AttributeError,
    in this case, the name of the class is stored in the global variable
    abstractClasses or noConcreteImplementation with False being returned.

    Return values:
    0: If not any of the SetInput() tests and the corresponding
             Update() are both true.
    1: If at least one of SetInput() tests and the corresponding
             Update() are both true.
    2: No observer could be added.
    3: If it is an abstract class.
    4: No concrete implementation.
    5: Class does not exist.

    :param: cname - the name of the class to be tested.
    :return: One of the above return values.
