                            IS_JSONS3


Similar to web2py's IS_JSON validator, but extended to handle
single quotes in dict keys (=invalid JSON) from CSV imports.

Example:

    INPUT(_type='text', _name='name', requires=IS_JSONS3())

    >>> IS_JSONS3()('{"a": 100}')
    ({u'a': 100}, None)

    >>> IS_JSONS3()('spam1234')
    ('spam1234', 'invalid json')
