PHP encapsulation solution—use Suit type

[mrmanc]

Is it possible for the $suit member to be of type Suit rather than type String? At the moment, I think the Suit class is just used as a place to store the array of suits. I’m thinking it should have a $name member (or perhaps $suitname) of type string, and then it could be used to provide a type to the member in PlayingCard. That’s the way we’ve done it in Java, but I don’t know if there’s a PHP reason not to do this 😃

If this change is made it might need to be applied to other branches which have the Suit class too.

Since I’ve merged #128 I thought it was worth creating an issue to keep track of this.
