	string constant private tokenName = "My ERC721 Token";
	string constant private tokenSymbol = "MET";
	uint256 constant private totalTokens = 1000000;
	mapping(address => uint) private balances;
	mapping(uint256 => address) private tokenOwners;
	mapping(uint256 => bool) private tokenExists;
	mapping(address => mapping (address => uint256)) private allowed;
	mapping(address => mapping(uint256 => uint256)) private ownerTokens;

	contract ERC721 {
	// ERC20 compatible functions
	function name() constant returns (string name);
	function symbol() constant returns (string symbol);
