// The Trader System

// traderLock: Prevents the player from regerating the trader's inventory before they leave the POI/Encounter
// traderInv: The global trader inventory, has a set of items for each tier of gear, pulled from the global item lists
// tempTraderInv: An array of items that the trader, when encountered, will be able to pull from for thier stock
// trader(): Called when a player barters with a trader. Fist checks to see if traderLock is false, then sets it to true.
//      Then uses the tier parameter to determine which inventory to pull from.
//      It then places the respective tier of equipment into the tempTraderInv array.
//      The trader now randomly picks 5 items from the tempTraderInv array and places them into tempTraderStock.
//      Had traderLock been true, the trader would present the previously generated stock.
//      Trader then uses the same system as the other stores to allow the player to buy and view items but with a custom message
//           The message is passed in as a parameter, and is displayed at the top of the trader menu.
