Added RecursiveMunch object.

Hi,

I felt the need to have a RecursiveMunch class, which is similar to DefaultFactoryMunch, except that it creates an instance of itself to generate values for missing keys, instead of a user-specified function.

Regards,

Guillaume Rochette

@GuillaumeRochette Thanks for contributing.

The RecursiveMunch code is duplication of DefaultFactoryMunch code, except for the value of default_factory member which is automatically set In RecursiveMunch.

Code duplication is a bad practice, please reuse the common code.

Hi,
Sorry, I've realised that I did not overload the copy() method, which causes an error.
Here is a corrected version:

class RecursiveMunch(DefaultFactoryMunch):
    """A Munch that calls an instance of itself to generate values for
        missing keys.

        >>> b = RecursiveMunch({'hello': 'world!'})
        >>> b.hello
        'world!'
        >>> b.foo
        RecursiveMunch(RecursiveMunch, {})
        >>> b.bar.okay = 'hello'
        >>> b.bar
        RecursiveMunch(RecursiveMunch, {'okay': 'hello'})
        >>> b
        RecursiveMunch(RecursiveMunch, {'hello': 'world!', 'foo': RecursiveMunch(RecursiveMunch, {}),
        'bar': RecursiveMunch(RecursiveMunch, {'okay': 'hello'})})
    """

    def __init__(self, *args, **kwargs):
        super(RecursiveMunch, self).__init__(RecursiveMunch, *args, **kwargs)

    @classmethod
    def fromDict(cls, d):
        # pylint: disable=arguments-differ
        return munchify(d, factory=cls)

    def copy(self):
        return type(self).fromDict(self)
