Document best practices for data serialization

[robert-zaremba]

Summary

Data serialization is at the core of every module. We need to process user input, serialize data in a storage and send the responses. We don't clearly document how we should do that.

Problem Definition

Dealing with data serialization can be problematic. We have bunch of functions in codec or Marshaler interface. We should document with examples what one have to do properly serialize data structures, interfaces and do interface implementation registration. Moreover we should document the best practice to manage a codec.Marshaler and avoid copying / recreating it through the simapp.

Proposal

Documentation + best practice document.
