class NodeFactory

The NodeFactory interface is used by the class loader to instantiate components.

The NodeFactory interface serves two purposes:

It allows for classes not derived from rclcpp::Node to be used as components.
It allows derived constructors to be called when components are loaded.

Subclassed by rclcpp_components::NodeFactoryTemplate< NodeT >
