def select_dict(coll, key, value):

    Given an iterable of dictionaries, return the dictionaries

    consider any to be a match.

    This is especially useful when calling REST APIs which
    return arrays of JSON objects. When such a response is
    converted to a Python list of dictionaries, it may be
    easily filtered using this function.
