 Note that `not_composable.cpp` instantiates a `rclcpp::Node` _without_ subclassing it.
 This was the typical usage model in ROS 1, but this style of coding is not compatible with composing multiple nodes into a single process.

 When a message arrives on that topic, the node prints it to the screen.
 We provide multiple examples of different coding styles which achieve this behavior in order to demonstrate that there are many ways to do this in ROS 2.
