fastforward
fun fastforward(syncedHeight: Long, syncedDate: Long, syncedHash: Hash256, txhist: List<TransactionHistory>)
If you provide the complete transaction history prior to the passed point, OR you provide the additional transactions from where this wallet currently is to the passed point, then you can call this function to jump the wallet forward. If you do not provide the complete transaction history, the wallet may attempt to spend already spent coins (if you miss a spend) or not have the complete balance (if you miss a receive). In the receive case, these funds are not "lost" since they are on the blockchain. They are simply inaccessible by this instance of the wallet. If you did a correct recovery, they would appear.
