flubberized sunburst to icicle (faster)

• sunburst from R htmlwidget sunburstR
• using d3.js and flubber
• d3.js source tree from Mike Bostock block D3 Source Treemap
• assembled with blockbuilder.org

This is a combination of quite a few numerous generous open-source contributions. Thanks especially to [Mike Bostock](https://bost.ocks.org/mike/) and [Noah Veltman](https://noahveltman.com/).
