Fixed Supply ERC20 Contract

FixedSupplyToken

The FixedSupplyToken smart contract implements all the mandatory ERC20 functions. They are:

totalSupply(), balanceOf(...), transfer(...), transferFrom(...), approve(...) and allowance(...)

Additionally, the approveAndCall(...) functionality is included so that the two operations of executing tokenContract.approve(targetContract, tokens) and targetContract.doSomething(...) (which will execute tokenContract.transferFrom(user, targetContact, tokens)) can be combined into a single approveAndCall(...) transaction. Please only use this functionality with trusted smart contracts, and with checks!
