List the address of this local test blockchain

var accounts;
web3.eth.getAccounts(function(err,res) { accounts = res; });
var account1 = accounts[0];
var account2 = accounts[1];

Set the address of Auction contract

Legends.deployed().then(function(instance){return instance.setSaleAuctionAddress(SaleClockAuction.address);});

Legends.deployed().then(function(instance){return instance.balanceOf(account1);});
Legends.deployed().then(function(instance){return instance.balanceOf(account2);});

List id of Legends owned by an address
