Quoting of Scalar Values in Generated Json

[j-mshaw]

Apologies if this is the wrong place for this question, but I think I may have stumbled onto either a weak point in documentation or a piece of missing functionality. The guide to writing a FlatBuffers schema on google.github.io states that "for compatibility with a JSON lint tool all numeric literals of scalar fields can be wrapped to quoted string". I looked through the possible flags listed in flatc.cpp and did not see one jumped out as one that would facilitate this functionality. Am I looking in the wrong place, or is this actually a missing piece of functionality?
