The whole idea is to be able to edit the data using standard java objects, then reading/writing to a file using those objects. Internally, we could easily have other data types as members of the blocks themselves, then allow API access to them.

I don't know the best way to go about it.. I just started coding and this is what happened. Above all, I want to make the code semi-easy to follow as that will lower the barrier to entry for contributions.
