-After defining the callback functions, we present now the `main()` function. First, some initialization for ROS 2 is necessary to create later rcl objects. That is an `allocator` for dynamic memory allocation, and a `support` object, which contains some rcl-objects simplifying the initialization of an rcl-node, an rcl-subscription, an rcl-timer and an rclc-executor.
