This command will simply pretty-print the contents of a MuPackage. My plan is to use it for my own development and debugging purposes, however, I suspect it will be generally useful (since MuIL can be quite verbose). Again, just scaffolding, but I'll flesh it out incrementally as more of the goo in here starts working...
