 Each order contains eleven key components:
 
-- The `offerer` of the order supplies all offered items and must either fulfill the order personally (i.e. `msg.sender == offerer`) or approve the order via signature (either standard 65-byte EDCSA, 64-byte EIP-2098, or an EIP-1271 `isValidSignature` check) or by listing the order on-chain (i.e. calling `validate`).

 - The `zone` of the order is an optional secondary account attached to the order with two additional privileges:
   - The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current counter at once by calling `incrementCounter`).
   - "Restricted" orders (as specified by the order type) must either be executed by the zone or the offerer, or must be approved as indicated by a call to `validateOrder` when the caller is not the zone.
