Now lets look at what we created. The transaction should have created a new account for the contranct in the trie.Lets test to see if it did.
function checkResults (cb) {
  // fetch the new account from the trie.
  stateTrie.get(createdAddress, function (err, val) {
    var account = new Account(val)

    storageRoot = account.stateRoot // used later! :)
    console.log('------results------')
    console.log('nonce: ' + account.nonce.toString('hex'))
    console.log('balance in wei: ' + account.balance.toString('hex'))
    console.log('stateRoot: ' + storageRoot.toString('hex'))
    console.log('codeHash:' + account.codeHash.toString('hex'))
    console.log('-------------------')
    cb(err)
  })
}
