Functions

func ShuffleWithNonceOrder 

func ShuffleWithNonceOrder(
	logger log.Log,
	rng *rand.Rand,
	numTXs int,
	ntxs []*NanoTX,
	byAddrAndNonce map[types.Address][]*NanoTX,
) []types.TransactionID

ShuffleWithNonceOrder perform a Fisher-Yates shuffle on the transactions. note that after shuffling, the original list of transactions are no longer in nonce order within the same principal. we simply check which principal occupies the spot after the shuffle and retrieve their transactions in nonce order.
