Oyster.ixi
Provides an API method Oyster.findSignatures that returns the signatures of the first* transaction associated with each given address.
This saves a roundtrip, the overhead of transmitting the whole transaction, as well as skipping any additional transactions findTransactions would return.
Additionally provides a more recent method Oyster.findGeneratedSignatures. This approach moves part of the datamap generation from the client to the server, easing the load on the clients upstream during download. Suggestions for a better method name welcome.
