[mlpack] Rocket injector demo

Some updates on Visualizer. The objective function simulation is also done!
See this Visualizer by FieryBlade (itch.io)
<https://fieryblade.itch.io/busteringaaz>. The blog is about 90% done, so
expect that soon :). I'm currently working on SoS kernel integration to use
bokeh as our plotting agent.
