// The ApproveAssignment operation approves the results of a completed assignment.
// Approving an assignment initiates two payments from the Requester's Amazon.com
// account
//
// * The Worker who submitted the results is paid the reward specified in
// the HIT.
//
// * Amazon Mechanical Turk fees are debited.
//
// If the Requester's account
// does not have adequate funds for these payments, the call to ApproveAssignment
// returns an exception, and the approval is not processed. You can include an
// optional feedback message with the approval, which the Worker can see in the
// Status section of the web site. You can also call this operation for assignments
// that were previous rejected and approve them by explicitly overriding the
// previous rejection. This only works on rejected assignments that were submitted
// within the previous 30 days and only if the assignment's related HIT has not
// been deleted.
