Proposal - Sourcery automatic code generation for boilerplate

[vaderdan]

Hi what do you think about Sourcery (https://github.com/krzysztofzablocki/Sourcery)
It generates generates some of the duplicate/boilerplate code for you

I think that model protocols for every model have identical structure and could be removed (moved to autogenerated file) with this
See this gist,

Basicaly it scans for classes that extends Automodel and make protocols with inputs/outputs from them
