var abi = /* abi generated by the compiler */
var ZombieFactoryContract = web3.eth.contract(abi)
var contractAddress = /* our contract address on Ethereum after deploying */
var ZombieFactory = ZombieFactoryContract.at(contractAddress)
// `ZombieFactory` has access to our contract's public functions and events

// some sort of event listener to take the text input:
$("#ourButton").click(function(e) {
  var name = $("#nameInput").val()
