WIP: Refactor VertexClustering worklet.
- Adds ability to map cell/point fields
- Adds temporary work around for slow ReduceByKey on TBB (#173 (closed))
- Use requested grid divisions in worklet, allowing anisotropic clusters.
- Select random point from cluster rather than averaging (this gives a better visual result).
Closes #161 (closed)
