Distance to the nearest cluster #146

Thanks for developing this module. It's been a great help. Is it possible to get the distance of every sample to all the clusters. Logically the nearest cluster will be the one to which the sample will get assigned eventually. I have a requirement in which , when a user enters a sample , instead of assigning a label to the sample, the model should print how similar the sample is to all the clusters. This can be the distance of the sample from all the clusters.

A trained kmodes instance will have the .cluster_centroids_ attribute. If you use that in combination with the dissimilarity function of your choice, you can determine the distance from a point to all centroids quite easily: dissim(centroids, curpoint)
