D'ni Museum exhibit #2: Numbers and units

Part of K'nehtis' museum of D'ni culture. This one contains banners describing some of the D'ni number system, along with a few demonstrations of simple arithmetic, measurement units, and time units. The only important factor, however, is the machine in the center; This is a tutoring device meant to actually teach visitors D'ni numbers, with buttons for both Surface and D'ni numbers.
Naturally, in-game, much of this will be useful for puzzles later on.
