Suggestion: Add possibility to explicitely specify input addresses in PrepareTransfers. about iota.go HOT 3 CLOSED

On the next branch the implementation of PrepareTranfers is aligned with iota.js. The given options can include a slice of Inputs which are simply addresses and their balance. The security level is needed to be able to determine how many transactions are needed to fit in the signature message fragments. The address/key index is needed to be able to compute the subseed which in turn is used to compute the private key which is used to sign the transactions.

Note that the client using any iota library should keep track of what addresses were used, their index and the overall security level used.

Thanks. That is more or less what I missed in the current version. Of course seed and security level is needed for signing. My comment is about redundant address generation sometimes. Also note that neither input address indices nor reminder address are needed if inputs exactly makes needed balance. That is how I use it very often.

The key index is needed to be able to compute the private key which is used to sign the input transaction (and the additional txs for the other fragments) whether there's a remainder or not.
