//! \brief PIMutexLocker
//! \details Same as std::lock_guard<std::mutex>.
//! When a PIMutexLocker object is created, it attempts to lock the mutex it is given, if "condition" true.
//! When control leaves the scope in which the PIMutexLocker object was created,
//! the PIMutexLocker is destructed and the mutex is released, if "condition" true.
//! If "condition" false this class do nothing.
//! The PIMutexLocker class is non-copyable.
