I am trying to run multiple circles along multiple paths. I need some help with:   - Run animation in one direction (down). I adjusted the yoyo setting to false but it still reverses direction (up) - Align the circles with the centre of each path. How are the x y offsets determined? - Refactor script. Also do I need to have 4 circle paths? - Any suggestions how this could be improved would be awesome.    Inspiration taken from https://www.quandl.com/#ember620
