Meet CoolDict: a python dict that always keeps its cool.

gistfile1.py

class CoolDict(dict):

    """A dict that returns an empty CoolDict if a key is not found.

    It litterally goes: 'Can't find your thing, but that's cool, don't care.'

    Example:
    >>> d = CoolDict()
    >>> d['value1']['value2'].get('value3', 0)
    0

    That could be very useful when dealing with JSON APIs with unreliable content,
    by saving you a ton of try/excepts.
