To load all objects in this example consult the ch.loader utility
file (note that the *.loader files are Prolog files).
You will need to also load the objects in the "roots" example.
You will need to consult the following files in the library directory:
events.loader, types.loader, and hierarchies.loader. Alternatively, you
may load the library/all.loader file to load all library entities.
