New to Steem, but interested in this project. I think this project needs a design of the datastructure. So some sort of Object Oriented (OO) design. Also an example function on instances of those classes will probabely clear things up. I now a bit about design patterns f.i. to generate instances of the classes. I think a preliminary (dummy) implementation can speed up the discussion. Also some unittests will help clear up the input and output for which the implementation will follow later. Can I help in this?
