I'm back till I have to study for finals^^, i would like to make some modifications to the queue now that I have much more experience with linked lists, thanks to my cs-102 class.

I added some commented code to brainstorm the revised queue system, which I wish to discuss with everyone later today.

Ohnobinki, I has lots of questions for you :p
