Class Summary

AbstractInstrument	The AbstractInstrument class can be used by an class wishing to implement the Instruement interface.
AbstractInstrumentable	Utility class to ease the construction of components that can be instrumented.
AbstractLogEnabledInstrumentable	Utility class to ease the construction of components that can be instrumented but must also implement LogEnabled.

NoopInstrumentManager	An InstrumentManager which doesn't do anything.
