[PD] Nestable Dictionaries in Pd

[João Pais]

Does the max documentation of flucoma has concrete examples of what 
you're looking for?

There is the purest_json library (which isn't vanilla), but maybe with 
some hacking it might be possible to read files. Not sure about writing, 
but my hacking isn't up to date with the current pd state.

We already have in our dataset object file support and single point entry and query but this allow batch dump and load. The structure is:
