Detailed Description

A wrapper to reserve an address from a wallet.

ReserveDestination is used to reserve an address. It is currently only used inside of CreateTransaction.

Instantiating a ReserveDestination does not reserve an address. To do so, GetReservedDestination() needs to be called on the object. Once an address has been reserved, call KeepDestination() on the ReserveDestination object to make sure it is not returned. Call ReturnDestination() to return the address so it can be re-used (for example, if the address was used in a new transaction and that transaction was not completed and needed to be aborted).

If an address is reserved and KeepDestination() is not called, then the address will be returned when the ReserveDestination goes out of scope.
