--------------------------------------

Please assign the ticket to me. I will create a feature branch and create a pull request for the implementation

> cKMeans implementation has been described here
> https://cran.r-project.org/web/packages/Ckmeans.1d.dp/index.html and https://journal.r-project.org/archive/2011-2/RJournal_2011-2_Wang+Song.pdf
> The algorithm described here is O(kn^2) where k: number of clusters and n: number of 1D points. But, there exists an efficient implementation in later versions of cKMeans which is O(knlog(n))
> cKMeans is faster than kMeans and also deterministic in nature. cKMeans is supposed to be one of the best clustering algorithms for clustering 1D points
