NOCC - Number Of Child Classes

Counts the number of classes which inherit from a particular class, i.e. the number of classes in the inheritance tree down from a class. Non-zero value indicates that the particlar class is being re-used. However, the abstraction of the class may be poor if there are too many child classes. It should also be stated that the high value of this measure points to the definite amount of testing required for each child class.
