Add tf debug visualizer/mode for the visualizer (ros-pkg ticket #418)

[hershwg]

Goal: Replace draw.sh in rosTF

It would draw each coordinate frame in real space with an arrow to it's parent.

It would need to have the viewing frame defined.

Advanced feature:
Set start and end frame(with times default to current) and show only the path between.

Disconnected frames could not be rendered (maybe have a drop down list of all tree roots to make obvious elements of the graph. (tf list output new feature needed)

If disconnected show up to parent for both sides(tf list output new feature needed)
