Usage

var chain = require('blockchain-api').chain,
    blockChain = new chain(); // Basic

let callback = (err, data) => console.log(err, data);

// Basics
blockChain.createWallet({
  password : 'MyPass',
  api_code : API_KEY,
  priv : null,
  label : null,
  email : null
}, callback);
blockChain.chart('typeChart', callback);
blockChain.stats(callback);
blockChain.ticker(callback);
blockChain.toBTC('USD', 100, callback);

// Exec
/* WALLET */
let wallet = blockChain.wallet(GUID, PASS1, PASS2);
let options = {
  from : 'Send from a specific Bitcoin Address (Optional)'
  fee : 'Transaction fee value in satoshi (Must be greater than default fee) (Optional)'
  note : 'A public note to include with the transaction -- can only be attached to transactions where all outputs are greater than 0.005 BTC.(Optional)'
};
wallet.balance(callback);
wallet.list(callback);
