kind of neat relationshippy thing
parma ham is a kind of ham, and ham is a kind of pork
So one day soon Snacksby will run through all of these relationships and know that when you say you've got parma ham you've also got pork. Right now, though, all it does is sit around and look pretty.
This is one of those sorts of features that's sure to run into bugs where it's searching the wrong way up the tree, or there's an infinite loop, or something is related to itself or whatever, so just be on the lookout for errors with it and let me know when you see 'em!
Oh and P.S., you don't have to set parma ham as a kind of pork - Snacksby's smart enough to jump through ham and to figure it out. So don't go around assigning something like velveeta extra sharp instant cheddar cheese to cheese!
