Objective-C counterpart for variadic argument contain matcher in Swift

[modocache]

I can write the following, very convenient, assertion in Swift:

// Swift

expect(["whale", "dolphin", "starfish"]).to(contain("dolphin", "starfish"))

But in Objective-C, I can't pass multiple arguments to contain, so I have to write two lines:

// Objective-C

expect(@[@"whale", @"dolphin", @"starfish"]).to(contain(@"dolphin"));
expect(@[@"whale", @"dolphin", @"starfish"]).to(contain(@"starfish"));

It'd be nice if Objective-C contain supported multiple arguments somehow (the same goes for beginWith and endWith).

For any of these matchers supporting multiple arguments, they need to be converted into a macro that implicitly wraps the arguments into arrays.
