public @interface UsingParameters
Annotation to use on plug-in classes such as the implementations
of IFilter or IPipelineStep to indicate what parameters class
they use. Classes that should not be used directly as plug-ins
(e.g. abstract classes) must not set this annotation.
Classes that use no parameters but need to be visible as plug-ins
must leave the default annotation's value.
That default value is IParameters.class but may change.
