[MC-CC] Tickets validator

---- Ticket validating machine
---- Tickets are being sold as labeled floppys
---- and are used on station to get a train to a demanded destination
-- os.pullEvent = os.pullEventRaw
---- Config
-- Sides of components

sides[2] = "back"   -- Transposer
sides[3] = "left"   -- Dispersers
sides[4] = "right"  -- Rail management
-- Rails' dispersers' colors
