Detailed Description

Protocol base class.

The Stimulus class and derived classes implement a range of stimuli. The stimulus contains input stimuli that can be applied throughout the domain, on specified regions determined by the derived classes of Stimulus, at specified frequencies determined by the derived classes of Protocol.
