Parse_wikidump: programmatic access

[nucflash]

Refactored parse_wikidump to allow programmatic access to its functionality, e.g., initialize db, and initiate downloads via code.

I think @IsaacHaze will be very unhappy when he sees his darling docopt replaced by ArgumentParser...

[nucflash]

Oh, I didn't know. I was inspired from how things are being done in xtas.

[larsmans]

That was written before I knew about docopt :)

OK, so docopt is the current default for parsing args?

[larsmans]

Yep.

[nucflash]

Alright. I'll revert the arg parsing logic to use docopt, then.

[larsmans]

I see how this is a useful feature, but I think it should be implemented differently, viz. by moving functionality from __main__.py (which is mean to be only a script entry point) to the module. E.g., move the functionality you might want to import from your code to parse_wikidump/__init__.py and then import it in __main__.py.

[nucflash]

Good points. Let me work on it a bit more and will hear from me soon.

But apart from the sadness, i'm all for this change (i did something similar in my joblib branch.)
