whitespace tweaks
earlier version of car-rollout.go (8eb1e2)
made it self-plotting (just pipe into gnuplot -)
setup without obstacles that always goes straight to the goal
self-contained plotting and tweaks to what is shown
support for creating animations as sets of PNG files
figured out the ffmpeg command to make a movie from the sequence of images
support for negative animation lengths: they are equivalent to lengths of path-size divided by abs(animation length), i.e. say -5 if you want to subdivide the motion into 5 chunks displayed at the same time
