To make sure that I get everything right, I built this code for
initializing the equipment library around the already existing JSON IO
loader. That is far from optimal because there is no type safety
whatsoever in these classes, and object properties are created in a
super ad-hoc manner at runtime. That is rather painful to work with
because there is no place anywhere in the code which would list all
properties that are *supposed* to be present.
