Numpy Integration

[poledna]

Hi,

Ive been using Munch and i love it, but i am missing a Munch numpy implementation.
what i have been doing recently is checking recursively all munches related to possible lists. When it finds a list it gets converted to numpy.
This is quite helpful for me, idk if is there a method that i have missed, but it is something that could be useful to the repo as a flag, such as lists2numpy when creating the munch.

    def convert_YAML2Struct(self, yaml):
        data = DefaultMunch.fromDict(yaml)
        for name in dir(data):
            current_key = getattr(data, name)
            setattr(data, name, self.check_munch_key(current_key))
            setattr(self, name, getattr(data, name))

    def check_munch_key(self, current_key):
        for i in dir(current_key):
            if isinstance(getattr(current_key, i), list):
                setattr(current_key, i, np.array(getattr(current_key, i)))
            elif isinstance(getattr(current_key, i), munch.DefaultMunch):
                setattr(current_key, i, self.check_munch_key(getattr(current_key, i)))
        return current_key

Best Regards,
Yuri
