+/*! \brief 2D array,
+ * \details This class used to store 2D array of any type elements as plain vector.
+ * You can read/write any element via operators [][], first dimension - row, second - column.
+ * The first dimension is Row, and you can operate with Row as PIVector<T>: modify any element, assign to another Row and etc.
+ * You can't add values to array, but you can modify any elements or create another PIVector2D.
+ * PIVector2D has constructors from PIVector<T> and PIVector<PIVector<T> >
