- added `Wikipedia` retriever. It is effectively a wrapper for `WikipediaAPIWrapper`. It wrapps load() into get_relevant_documents() - sorted `__all__` in the `retrievers/__init__` - added integration tests for the WikipediaRetriever - added an example (as Jupyter notebook) for the WikipediaRetriever
