    Class Operations
    ================
    Timer objects start running when they are constructed.  
    They count time in milliseconds.  If started, they reset
    their time count from that instant.  When stopped they 
    remember the elaspsed time since being constructed or 
    started, whichever is the more recent.

    timer t1, t2;     // start timers t1 and t2
    t1.start();       // restart timer t1
    t2.stop();        // stop t2
    t1.elapsed();     // return number of msecs since start
    t2.elapsed();     // return number of msecs since constr.
