 * Synopsis:
 *      Timer is a class to provide simple timing functions:
 *
 *      Here is an example of how to use it:
 *
 *                Timer timer;
 *
 *              timer.start();
 *              .. do some tasks for timing ..
 *              timer.stop();
 *
 *              long clock = timer.getClocks();     // get CPU clocks
 *              long seconds = time.getSeconds();   // get seconds
