/***************************************************************************
 * IpplCounter - a simple megaflops counter that accesses hardware counters
 * for measureing megaflop performance.
 *
 * To use these counters:
 *   1. Create a counter.
 *       example:   Counter FFTcounter("FFT");
 *
 *   2. Locate the function which you would like to measure and start the
 *       counter by placing the startCounter() method before it.  Then, stop
 *       the counter after it by using the stopCounter() method.
 *       example:   FFTcounter.startCounter();
 *                  fft->transform(....);
 *                  FFTcounter.stopCounter();
 *
 *   3. Use the printIt() method to print to the screen.
 *       example:   FFTcounter.printIt();
