/** \class PIMutex
* \brief Mutex
* \details
* \section PIMutex_sec0 Synopsis
* %PIMutex provides synchronization blocks between several threads.
* Using mutex guarantees execution of some code only one of threads.
* Mutex contains logic state and functions to change it: \a lock(),
* \a unlock() and \a tryLock().
*
* \section PIMutex_sec1 Usage
* Block of code that should to be executed only one thread simultaniously
* should to be started with \a lock() and ended with \a unlock().
* \snippet pimutex.cpp main
* "mutex" in this example is one for all threads.
