/****************************************************************************
 *
 * This class provides a generic interface for the decision making tools.
 * 
 * The idea is to enable the following methods, the implementation of which
 * will depend on the model being used:
 *
 * constructor -- Expected to take an instance name.
 * loadConfig  -- Load configuration file.  ALSO: initialize data manager.
 * update    -- update the state and return true (fire) or false (don't fire)
 * reset     -- reset internal state
 *
