Add class(es) for table results

[derikb]

As used in Randomizer, they tend to be:

• table {String} perhaps with special method for "isDefault" where name === default
• result {String}
• desc {String} Extra... text...

Would simplify some kind I think to be able to have a class for this. Maybe a class for a collection of them, since tables can return an array of results. That would aid in formatting table result output a lot I think.
