Title: figured out graphviz gem!

sweetness- i did an overhaul of the code to auto-generate the png file. now it uses the graphviz gem (instead of writing a 'dot' file and then using 'dot' binary to create the png). and it actually creates the png automagically after each question! i decided to remove the labels for the transitions from the png because it gets too cluttered. i think it looks better this way, what do you think.

can you review and merge this please?
