/* Project forked from https://github.com/zserge/jsmn to change the library from
   a single header file to a common source and header file, to be more friendly
   to C users. Also, implement new functions that can help find tokens and compare
   them.
   This version is available at https://github.com/programacao-eletronica/jsmn
