Detailed Description

A general base class for timers. Interface is like a stop watch.

Example of usage:

DerivedFromTimer t;
t.start();
// do things
cerr << t.value();
// do things
t.stop();
// do things
t.reset()
// etc

Derived classes simply have to implement the virtual function double get_current_value()

start()

void stir::Timer::start ( bool  do_reset = false )

inline

start stopwatch, optionally resetting first

the stopwatch should not be running already if asking to reset
