/**
 * An Immutable List class in similar to a Scala List. It's important to point out that this list is not infact a real
 * Linked List in the traditional sense, instead it is backed by a AypeScript/JavaScript Array for simplicity and
 * performance reasons (i.e., arrays are heavily optimized by VMs) so unless there's a good reason to impliement a
 * traditional List this will remain this way. Externally the List Interface will ensure immutabliy by returning new
 * instances of the List and will not mutate the List or the underlying Array in any way.
