In an effort to give names to core concepts in the library, replace the
current way of passing around tuples (of varying length and content)
with appropriately named structs.
As a consequence of creating `Player.{V1, V2}` and `Result`, a variety
of functions that extracted values out of the tuples have either been
removed or changed to access struct fields instead.
