Hierarchical Clustering Addition

[BassCoder2808]

I would like to add add code for Hierarchical Clustering which I found out is missing/not available in machine_learning folder.
If the solution already exist I would request someone to add the relevant files under the machine_learning folder.
If the solution does not exits I would like to work on it.
