Create UI module for common components

Browse source 
Create UI.elm to house components like `button`, which is a simple HTML button
with `focus:outline-none` applied as a `class`, which is an accessibility
feature that I don't need for this touch-screen application.

I like this pattern more than my more opinionated patterns for UI modules in Elm
where I'd define all of the arguments as a record type (i.e. kwargs).
