Should we add main methods? #8
Description
Both mergesort and arraymerge only provide test suites, and no main. Should we provide mains so people can run them from the command line? I'm not really sure, TBH. Both strike me as more "library" projects than main projects, so I feel like running them through the tests seems to be the "right" thing to do. That said, there are always questions about this, though, so it seems like it's worth raising the issue.
