Method to check to see if a transaction can be reattached to the Tangle

[todofixthis]

From https://github.com/iotaledger/iota.lib.js#isreattachable (with a few modifications):

isReattachable

This API function helps you to determine whether you should replay a transaction or make a completely new transaction with a different seed. What this function does, is it takes one or more input addresses (i.e. from spent transactions) as input and then checks whether any transactions with a value transferred are confirmed. If yes, it means that this input address has already been successfully used in a different transaction and as such you should no longer replay the transaction.

Input

api = Iota(...)
ir_result = api.is_reattachable(addresses)

• addresses: Iterable[Address] input addresses from the transaction(s).

Returns

{'reattachable': List[bool]} — similar to getBalances, the result contains a list of booleans corresponding to the addresses that were provided in the request.

This method is also really important for security because Winternitz signatures become exponentially less secure after each re-use.

Note: In the latest version of the JS lib, this method was renamed to isReattachable and accepts multiple addresses now. I've updated the issue description.
