 - When taking from the order book no tokens/nfts are transferred. Instead the orderId is stored in a claimable array
 - The tokens claimable are packed with 3 orders per storage slot

+The order book is kept healthy by requiring a minimum quantity that can be added - partial quantities can still be taken from the order book. Cancelling orders shifts all entries at that price level to remove gaps.
 
 Constraints:
 
 - The order quantity is limited to ~16mil
 - The maximum number of orders in the book that can ever be added is limited to 1 trillion
 - The maximum number of orders that can be added to a specific price level is between 4.2 - 16 billion
