Exporting functions from submodules

[gagdiez]

Right now, there is no simple way to export a function that was imported from a submodule. This makes it hard to modularize an assembly contract, therefore complicating the whole developing process.

I would love if we could have the option to make:

import {f1, f2, f3 ... fn} from './bar'}
export {f1, f2, f3 ... fn}

I also find this feature useful. Was surprised when I could not call a function imported this way
