Strongly typed alternative to null. The Option type in this package is based off of the Option typeclass from Scala and the Maybe monad from Haskell.

`Option` itself is just an interface. Two classes in this package implement the `Option` interface and they are `Some` and `None`. The convention is to have functions return `Option` types and it will either contain `Some` value or `None` at all. This creates a type safe alternative to returning null in the absence of a value.

In addition to the added type safety, the `Option` type is monadic, so `Option` types are highly composable. This allows you to eliminate a lot of the typical null checking boiler plate code you'd normally have to write and encourages you to write in a more expressive style.
