I have a generic System type, which I'd like to instantiate non-generic instances of, based on a few different ComponentTypes in my project. What's the best way to create these System instances? - - - In the past, I believed this was one potential use of ICustomBootstrap. But I've since learned that ICustomBootstrap is meant for creating your own custom Worlds. - - - I'd like to add these System instances to the default World. What would be the best tool for this job? Thanks for any advice.
