added a few more features to qc

[davidedelvento]

UPDATE: Dan, I believe the current status of my repo now is good enough to be pulled. Please take your time to look at what I did (and possibly discuss it), but I'd appreciate if you give me acknowledgment about reading this message (since I am not sure if the new github notification strategy will notify you or if I should try to ping you in a different manner). Thanks, Davide

OLD MESSAGE: Dan, I forked your qc repo and I think made very nice improvements in functionality (even if they came from a very small number of lines of code). I think the current status is not yet "good enough" to be pulled, but I'm making the request anyway so if you have spare time during the weekend you could:

• get directly involved in what I am doing
• just participate in the discussion (see my commits - you might want to join the conversation)
• at least familiarize yourself with what I am doing for when I'll made the "real" pull request.

Cheers, Davide
