Handle type aliases

[niran]

I copied types over from my contract and ran into an error when it tried to parse lengths that were missing. The workaround is easy, but it'd be nice if it were safe to copy the types from the contract.

Sorry @niran I am not sure exactly which types this is an issue with? Would you mind posting some examples?

[niran]

uint and int are aliases for uint256 and int256. byte is an alias for bytes1.

@niran those aliases are implemented. Where are you getting an error?

[axic]

@niran apparently byte is a new addition as hence it is not included. It needs to go into the ABI first, but happy to support it after.

uint failed for me here if I recall correctly: https://github.com/axic/ethereumjs-abi/blob/master/lib/index.js#L78

It tries to parse the size, but there isn't one.

[axic]

@niran the translation is done earlier: https://github.com/axic/ethereumjs-abi/blob/master/lib/index.js#L178 and https://github.com/axic/ethereumjs-abi/blob/master/lib/index.js#L217

It should be (u)int256 by the time it gets into the single item encoding

What's the status of this, is this a bug or was this wrong use of the API?
