+ * Description: Firstly, the memory allocated for *dest is released. After this, new memory is allocated
+ *              and string from src is copied to newly created location. *dest is pointing to new string.
+ * Arguments: dest - pointer to pointer to string previously allocated by malloc family functions.
+ *                   If dest is NULL, memory will be allocated and returned from the function. In latter
+ *                   case dest will be unchanged
+ *            src - string containing data for copying. If src is NULL, new memory is not allocated, but
+ *                  the old one is still released.
