'Process data through this node. This method is called any time the flowchart
wants the node to process data. It will be called with one keyword argument
corresponding to each input terminal, and must return a dict mapping the name
of each output terminal to its new value.
This method is also called with a \'display\' keyword argument, which indicates
whether the node should update its display (if it implements any) while processing
this data. This is primarily used to disable expensive display operations
during batch processing.'
