There is no clustering apart from the EM for Gaussian mixtures already in the project. Hence, I would like to implement a kmeans algorithm both the hard clustering version which is common and the soft clustering derivation of the kmeans algorithm. Once I get a go-ahead, then I will proceed to raising a PR within the next few days.

The hard version of K-means will follow the implementation in this slide

The soft version of K-means will also follow the implementation in this slide

I have written up both efficient implementations before checking the contribution guide that specifies that there must be an issue opened. Please give your approval and I will raise the PR right away
