no wallet api

[spicylobe]

Some of the cooler language clients support the /wallet api. This would be a significant improvement to the the java client. This would seem to require:

• a new WalletService with these methods http://dev.blockcypher.com/#wallet-api
• new model classes:
  • Wallet http://dev.blockcypher.com/#wallet
  • AddressKeychain http://dev.blockcypher.com/#addresskeychain
  • HDWallet http://dev.blockcypher.com/#hdwallet
  • HDChain http://dev.blockcypher.com/#hdchain
  • HDAddress http://dev.blockcypher.com/#hdaddress
• update Address to include "wallet" and "hdWallet" (assuming we ever return those)
• update Webhook and WebhookService to include a "walletName"
• [probably more stuff]

Ideally, we could also get some helper to generate the "extended public key" necessary for HD wallets.

A wallet API would be good. In the meantime, for anyone who wants to spend from a wallet without specifying input transactions, you can do it like this:

String transactionJson = "{" +
                        "\"inputs\":[{\"wallet_name\":\"" + WALLET_NAME + "\"," +
                        " \"wallet_token\":\"" + TOKEN + "\"}]," +
                        "\"outputs\":[{\"addresses\": [\"" + sendToAddress + "\"], " +
                        "\"value\": -1}]}"; // -1 means sweep all value from all addresses

                IntermediaryTransaction unsignedTx = context.getTransactionService().newTransaction(transactionJson);

I'm tagging this as help wanted as this would be really useful.
