// Class implementing several action records of the type where
// the player has to press a sequence of buttons in a certain order.
//		- OrderingPuzzle: The most simple type. Allows for manual depressing of buttons
//		- PianoPuzzle: Buttons always auto-depress; every button has unique sound file
//		- OrderItemsPuzzle: Buttons may depress or stay down, but player can't depress manually.
//			Has second button state that is activated when player is holding a specific item. (see fingerprint keypad puzzle in nancy4)
//		- KeypadPuzzle: Buttons may auto-depress, stay down, and can be depressed manually by player.
//			Adds an optional button for manually checking for correct solution, number of possible buttons is 30.
//		- KeypadPuzzleTerse: Same as above, but data format is shorter, and supports up to 100 buttons
