* Assume C++11
We already assume C++11 elsewhere, so all pre-11 `#ifdef` branches are
dead code at this point. Fixes issue #1591 because we can just use
`std::isfinite` etc.
assume C++11 in json_reader.cpp as well
apply clang-format
* valueToString: simplify lookup of special float name
Google advises its employees to add Google Inc. as an author, but that hasn't
been done yet and would be super inconvenient. So instead I've refactored the
file to refer to "The JsonCpp Authors", which are listed in the AUTHORS file.
The AUTHORS file itself is generated via:
git log --pretty="%an <%ae>%n%cn <%ce>" | sort | uniq
Plus the addition of "Google Inc." as a copyright author. (Google owns the work
of anyone contributing from an @google.com address, for example.)
The list contains some probable duplicates where people have used more than one
email address. I didn't deduplicate because -- well, who's to say they're
duplicates, anyway? :)
