Using this base class aids Scale in standardizing the appearance of all its error messages.

Errors are unchecked exceptions and do not have to appear in the signature of the method that throws them.

To define a new error, a developer should define a new class that inherits either from this class or one of its descendents and write a constructor which can be used in a throw statement.
