   @emkornfield I had checked earlier, and those generated files didn't have 
the actual Flatbuffers schema for the `Schema` class in them, which is what is 
needed to generate a `flatbuffers::Parser` instance. But I had another look, 
and I found some support to serialize a binary version of that definition with 
`flatc` which can then be loaded in a `Parser` class instance. I assume that's 
also faster than parsing the .fbs text file, so better all around.
   
   Next step is the error handling. And then the opposite direction, with 
`FromJson()`. (I put that as a static class method instead of a constructor to 
be able to report errors more easily. Let me know if you feel that's not the 
right call.)
