More Traffic Control Updates

Always more stuff to change. I updated a bunch of different things, mostly clarifications, and added some nice graphical representations of class hierarchies.

Now I need to rewrite the example configurations. The HTB example is silly and I’m using a modified PRIO setup with a classful TBF qdisc instead of using HTB for my present configuration. Something about HFSC would eventually be nice.

Presently I’m writing a diagnostic and monitoring section.
