These constants are used by handler functions that
are called when a JSON value is encountered by the 
JSON parser. These identify the type of the JSON value.
The values will already have been converted, but
the start and end array and object events won't have
a type.

This is a package that allows conversion to and from data
        in Javascript object notation (JSON) format. This allows R
        objects to be inserted into Javascript/ECMAScript/ActionScript
        code and allows R programmers to read and convert JSON content
        to R objects. This is an alternative to rjson package. That
        version is too slow for converting large R objects to JSON and
        is not extensible, but a very useful prototype.  It is fast for
        parsing. This package uses methods, vectorized operations and C
        code and callbacks to R functions for deserializing JSON
        objects to R. Verison 0.4 of this package uses a new native
        parser, implements the transformation code in C and allocates
        memory efficiently (rather than concatenating because of event
        driven parsing). The result is a significantly faster parsing
        of large JSON documents.
