Adding mw.smw.ask to available smw functions

[oetterer]

In reference to #11 I added 'ask' to the available lua functions. This PR also includes a section in the documentation about the differences between the ask and getQueryResult.

Requires a rebase after #23 has been merged.

Probably a matter of personal style but when creating a large dataProvider, I would go for individual providers because in case the test fails you would need to count/find the array entry and change the structure which may prove difficult in some situations.

$provider['Can explain the purpose'] = [

];

// or leave it and be assigned a number
$provider[] = [

];

return $provider;

Nothing that prevents it from merging.

What happens when you use format=debug with the ask parameters? format=debug doesn't return a QueryResult object (returns a string).

Thanks for the suggestion. Was looking for a way to annotate tests. Will work this in, next time I touch the tests.

Thank you very much for pointing this out. Did not know that. Put a PR (#26) online with a suggestion to handle this.

I guessed that much hence my inquiry.
