//! \ingroup OpenMaya
//! \brief This class works similar to timerX MEL command.
/*!
  MTimer class provides the functionality for calculating the time
  elapsed/consumed in executing a particular portion of the code. The
  portion of the code to be timed is embedded inbetween the calls
  to'beginTimer()' and 'endTimer()'. A call to 'elapsedTime()' gives
  the time spent in executing that portion of the code.  The
  calculated time in seconds will be with 2 decimal accuracy.
