        """Constructor for JSONEncoder, with sensible defaults.

        If skipkeys is false, then it is a TypeError to attempt
        encoding of keys that are not str, int, long, float or None.  If
        skipkeys is True, such items are simply skipped.

        If ensure_ascii is true, the output is guaranteed to be str
        objects with all incoming unicode characters escaped.  If
        ensure_ascii is false, the output will be unicode object.

        If check_circular is true, then lists, dicts, and custom encoded
        objects will be checked for circular references during encoding to
        prevent an infinite recursion (which would cause an OverflowError).
        Otherwise, no such check takes place.

        If allow_nan is true (default: False), then out of range float
        values (nan, inf, -inf) will be serialized to
        their JavaScript equivalents (NaN, Infinity, -Infinity)
        instead of raising a ValueError. See
        ignore_nan for ECMA-262 compliant behavior.

        If sort_keys is true, then the output of dictionaries will be
        sorted by key; this is useful for regression tests to ensure
        that JSON serializations can be compared on a day-to-day basis.

        If indent is a string, then JSON array elements and object members
        will be pretty-printed with a newline followed by that string repeated
        for each level of nesting. ``None`` (the default) selects the most compact
        representation without any newlines. For backwards compatibility with
        versions of simplejson earlier than 2.1.0, an integer is also accepted
        and is converted to a string with that many spaces.

        If specified, separators should be an (item_separator, key_separator)
        tuple.  The default is (', ', ': ') if *indent* is ``None`` and
        (',', ': ') otherwise.  To get the most compact JSON representation,
        you should specify (',', ':') to eliminate whitespace.

        If specified, default is a function that gets called for objects
        that can't otherwise be serialized.  It should return a JSON encodable
        version of the object or raise a ``TypeError``.

        If encoding is not None, then all input strings will be
        transformed into unicode using that encoding prior to JSON-encoding.
        The default is UTF-8.

        If use_decimal is true (default: ``True``), ``decimal.Decimal`` will
        be supported directly by the encoder. For the inverse, decode JSON
        with ``parse_float=decimal.Decimal``.

        If namedtuple_as_object is true (the default), objects with
        ``_asdict()`` methods will be encoded as JSON objects.
