The SimpleDecoratorNode provides an easy to use DecoratorNode. The user should simply provide a callback with this signature.
BT::NodeStatus functionName(BT::NodeStatus child_status)
This avoids the hassle of inheriting from a DecoratorNode.
Using lambdas or std::bind it is easy to pass a pointer to a method.
