The CalculatorProbeSet interface captures a set of probes required by a
calculator. It replaces the
List which was passed to a calculator
factory method. Probes contained in a configuration can be referred to by a
semantic identifier.
Usually it is not necessary to implement this interface directly, instead use
an appropriate factory method of
DefaultCalculatorProbeSets. The only
exception is an extension which contributes a new type of calculator, to
which the current kinds of configurations are not suitable.
