Detailed Description

Tool to measure elapsed real and process times.

Timer is started by either passing a string to the ctor, or callign start. The string passed is printed on all messages to help identifying the timer.

Elapsed time is printed on calling elapsed (timer keeps running) or stop.

Calling stop, stops the timer. The same, if the timer goes out of scope.

Elapsed time is printed as:

 'REAL TIME' (u 'USER TIME' s 'SYSTEM TIME' c 'TIME OF CHILDREN')

In brackets the time elapsed since a previous call to elapsed. All units are seconds.

 Measure m( "Parse" );
 ...
 m.elapsed();
 ...
 m.elapsed();
 ...
 m.elapsed();
 ...
 m.stop();

 // START MEASURE(Parse)
 // ELAPSED(Parse)  0 (u 0.13 s 0.00 c 0.00)
 // ELAPSED(Parse)  0 (u 0.15 s 0.02 c 0.00) [ 0 (u 0.02 s 0.02 c 0.00)]
 // ELAPSED(Parse)  0 (u 0.17 s 0.02 c 0.00) [ 0 (u 0.02 s 0.00 c 0.00)]
 // MEASURE(Parse)  0 (u 0.17 s 0.02 c 0.00) [ 0 (u 0.00 s 0.00 c 0.00)]
