    Validate All Fields in an Elm Form Using Applicatives

    We have run into the problem of of having too many inputs and map2 only being a binary function. We could make a ternary map3 function but eventually we'll run into the same issue.

    In this lesson we'll learn to write a function that will validate an arbitrary number of fields on the form, and compute an overall result that tells you whether the form is valid as a whole.
