        Converts an object and returns a ``JSON``-friendly structure.

        :param obj: object or structure to be converted into a
                    ``JSON``-ifiable structure

        Considers the following special cases in order:

        * object has a callable __json__() attribute defined
            returns the result of the call to __json__()
        * date and datetime objects
            returns the object cast to str
        * Decimal objects
            returns the object cast to float
        * SQLAlchemy objects
            returns a copy of the object.__dict__ with internal SQLAlchemy
            parameters removed
        * SQLAlchemy ResultProxy objects
            Casts the iterable ResultProxy into a list of tuples containing
            the entire resultset data, returns the list in a dictionary
            along with the resultset "row" count.

            .. note:: {'count': 5, 'rows': [('Ed Jones',), ('Pete Jones',),
                ('Wendy Williams',), ('Mary Contrary',), ('Fred Smith',)]}

        * SQLAlchemy RowProxy objects
            Casts the RowProxy cursor object into a dictionary, probably
            losing its ordered dictionary behavior in the process but
            making it JSON-friendly.
        * webob_dicts objects
            returns webob_dicts.mixed() dictionary, which is guaranteed
            to be JSON-friendly.
