[Smtk-developers] JSON in SMTK

[David Thompson]

I think since it is header-only that we would not need to mangle it, but rather install it inside the smtk include tree (e.g., include/smtk/thirdparty/nlohmann_json) so that others can use exactly the version SMTK is compiled with. We can define a macro (yes!) for nlohmann's include path so that it is possible to use an external version or third party version:

#include "smtk/Options.h"
#include SMTK_NLOHMANN_JSON_H

Attached is my experiment with syntax and getting UUIDs and arrays of UUIDs serialized. nlohmann does not require calls to converter functions nor does it even require a converter... UUIDs just worked (however, we probably want a converter as its default behavior writes UUIDs as JSON arrays of unsigned integers).
