0010  Description: Base class for classes that 'watch' what OscarProducer does
0011 internally
0012
0013  Usage:
0014     By itself, this class actually does nothing except allow dynamic loading
0015 into the OscarProducer.  To do useful work, one must inherit from this class
0016 and one or more 'Observer<T>' classes.
