I didn't reimplement the variant-storage concept, I used a union. This
does away with all the unnecessary baggage of having to support
arbitrary types with arbitrary exception specifications. In my case
the notional "variant" is always instantiated with the same types,
thus avoiding bulk in the headers.

A goal of this JSON library is to have very fast compilations, I have
avoided templates wherever possible (especially in the vocabulary
types) and when there are member function templates I have used
techniques to reduce the number and size of instantiations.
