Detailed Description

template<unsigned NUM_EVENTS, class CONCRETE>
class GenericEventHandler< NUM_EVENTS, CONCRETE >

A generic base class providing the functionality for timing various events. Subclasses provide the event codes and names; see HeartEventHandler for an example.

Note: this class assume that, for any given concrete class, the last event represents the total time, and thus wraps all other events.

The methods in this class are not implemented separately as then they would not be inline, which could impact performance; we generally want timing routines to be very lightweight.
