It will be configured by the opts hash. opts can have the following keys:

opts can have the following keys:

- max_nesting: The maximum depth of nesting allowed in the parsed data structures. Disable depth checking with :max_nesting => false|nil|0, it defaults to 100.

- 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. It’s not possible to use this option in conjunction with the create_additions option.

      (Float) when parsing decimal numbers. This class must accept a single
