I need to store and pass around several paired objects:

1) An `NSString` of a filename such as "sprite.png"

2) `BOOL` value for whether or not that sprite should be animated.

So basically, I have a bunch of sprites, and each of them are either animated or not.

I thought I could use an `NSDictionary` to store everything, but I think using `[NSNumber numberWithBool:YES]` as the key only allows you to have a single entry with that value.

What sort of structure is most appropriate to pass along that can satisfy my requirements?
