* * *allow_nan*: If set to true, allow NaN, Infinity and -Infinity in
* defiance of RFC 4627 to be parsed by the Parser. This option defaults to
* false.
* * *symbolize_names*: If set to true, returns symbols for the names
* (keys) in a JSON object. Otherwise strings are returned, which is also
* the default.
* * *create_additions*: If set to false, the Parser doesn't create
* additions even if a matchin class and create_id was found. This option
* defaults to true.
* * *object_class*: Defaults to Hash
* * *array_class*: Defaults to Array
