Algorithm 3: Token contract function

function totalSupply() constant returns (uint256 totalSupply)

function name() constant returns (string_name)

function symbol() constant returns (byte32_symbol)

function decimals() constant returns (uint8_decimals)

function balanceOf(address_owner) constant returns (uint256 balance)

function transfer(address_to,uint_value) returns (bool)

function transfer(address_to,uint_value,bytes_data) returns (bool)

function tokenFallback(address_from,uint_value,byets_data)
