     A parser class which allows to incrementally parse json elements and emit json parse events instead of parsing a json

     <p/>
     The parser can also parse entire object or array when it is convenient, for instance a very large array
     of small objects can be parsed efficiently by handling array <i>start</i>/<i>end</i> and <i>object</i>
     events.
