When terminal interacted with, load "PLEASE WAIT" textbox
	Convert mon data to wool lines, null out trade_data.nbt structure, and generate save structure block for encoded data

Load saving instructions:

	   in structures
	   folder
	5. Quit world and
	   re-join

	Pressing B opens a cancel trade dialog
		Do you want to \n stop trading?
			Yes - Closes trade interaction fully
			No - Removes cancel trade dialog and continues presenting how to trade steps

After relogging, run integrity check to see if new trade_data.nbt exists and does not match the original
	If either condition fails:
		Valid trade data
		not	detected.
		Please try again.
			Close trade session on a/b
	If valid, load initial trade screen with mon data
		Cancel closes all trade dialogs
		Selecting a mon loads options menu (stats/trade)

In options menu
	B button returns to mon selection

	B button deletes characters only

	If valid code:

		Trade confirmed!

		Codes for partner
		Code 1: ####
		Code 2: ####

		Once both players
		see this screen,
		press A.

-----------------------------------------

Could still have a case where one player completes the trade with Code 2 and presses A before giving the second player their code 2, causing one trade to succeed while the other fails.

A more secure confirmation method would have each player select trade, generate a new structure block, have players exchange files again, relog, and verify that both structure blocks have trade selected.  But requiring 2 relogs is painful, especially given loading times on the world.
