Thin wrapper around dict or list that provides easy access to nested datastructures that may contain lists, dicts and simple types.

Values can be accessed via a path notation (default: dot-separated).

Supports getting, modifying, appending and removing values from the nested data structure, iteration over a path pattern and in (contains) operation for paths.

Supports either "silent mode", where trying to access non-existing data just returns None, or can throw KeyError of any of the items along the path does not exist.

Does NOT create a copy of the data structure, which can be very handy for processing existing complex data (e.g. parsed JSON value).
