Let the users have metadata (e.g. title) if they need it. Added an argument in WikiCorpus __init__() to specify if metadata is needed. Previously, it was set to False and could not be toggled.
Make Wikipedia corpus metadata accessible.
Allow users to access metadata by allowing self.metadata in WikiCorpus to be set by a parameter. However, Dictionary() raises "TypeError: decoding to str: need a bytes-like object, list found" if metadata is returned. So, introduced a dictionary_mode parameter in get_texts() so that metadata bypasses the dictionary, and goes directly to the user.

What "corpus"? Please make the docstring more explicit, less cryptic (and properly capitalized and punctuated, like the others).

Background: I'd like article text along with the title for my project. The current implementation provides no way for the users to retrieve the title (i.e. metadata).
Allow users to access metadata by allowing self.metadata in WikiCorpus to be set by a parameter. However, Dictionary() raises "TypeError: decoding to str: need a bytes-like object, list found" if metadata is returned by get_texts(). So, introduced a dictionary_mode parameter in get_texts() so that metadata bypasses the dictionary, and goes directly to the user (if user sets metadata = True).
