Some RapidJSON features are configurable to adapt the library to a wide

features can be configured in terms of overriden or predefined
preprocessor macros at compile-time.
Some additional customization is available in the \ref RAPIDJSON_ERRORS APIs.
\note These macros should be given on the compiler command-line
(where applicable) to avoid inconsistent values when compiling
different translation units of a single application.

In order to avoid symbol clashes and/or "One Definition Rule" errors
