refactor dependencies and installation

There are hard copies of the graphviz and pyyaml dependencies included
in the repo. Remove these.

Sort out installation and dependency handling by writing a functional
setup.py script. Rename top level documentation. Refactor wireviz.py
slightly to allow it to run as an installed script.
