+ * @brief Thread class
+ * \details This class allow you parallelize loop.
+ * 
+ * \section PIThreadPoolLoop_sec0 Usage
+ * This class designed to replace "for(;;)" statement in very simple way.
+ * In constructor several threads created, then by "setFunction()" method
+ * you should pass body of your loop, and then call "start()" or "exec()".
+ * Every thread take loop counter and execute your function until all
+ * counter range is passed.
+ *
+ * Example:
+\code{.cpp}
+PIVector<int> data(10, [](int i)->int{return i;});
+
+piCout << data; // {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
+
+PIThreadPoolLoop pool;
+pool.exec(0, data.size(), [&](int i){ // parallel analogue "for (int i = 0; i < data.size(); i++)"
+	data[i] = data[i] + 10;
+});
+
+piCout << data; // {10, 11, 12, 13, 14, 15, 16, 17, 18, 19}
+\endcode
+ *
+ * Equivalent to:
+\code{.cpp}
+PIVector<int> data(10, [](int i)->int{return i;});
+
+piCout << data; // {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
+
+pool.setFunction([&](int i){
+	data[i] = data[i] + 10;
+});
+pool.exec(0, data.size());
+
+piCout << data; // {10, 11, 12, 13, 14, 15, 16, 17, 18, 19}
+\endcode
+ *
+ * \section PIThreadPoolLoop_sec1 Important
+ * Due to multithreading it`s very important to protect output data of loop body, use mutex.
+ * Also remember that execution order is undefined and you shouldn`t use global variables in
+ * your function. Use local variables and lambda capture.
