Use Sealed Classes

[nschwermann]

• Refactor to sealed classes - This keeps invalid TrollNumbers from being created and is also a perfect use case and example of creating algebraic data types using sealed classes in Kotlin

• Update docs

• No longer need brackets for adding two troll number expressions
  many-one + many-one = many-many-two

• Officially geeking out. Numbers greater than 16 should be lots and lots not many and many according to wiki
  Discword Wiki - TrollNumbers

This is a great improvement over my implementation. However I'm not sure how to deal with it because my implementation is described in the article and by changing the implementation we kind of lose the connection between them. What do you think about adding another kotlin folder instead, calling it kotlin-with-sealed-classes or something like that?

Can you update your article so the link points to a specific commit? Then you can write a follow-up about your improvements and what you've learned if you like :) if you have any questions to get a deeper understanding of the changes I'm happy to help.
