Converting this to draft as the implementation is not yet finished.

[nakul-krishnakumar]

As discussed with @kgryte in the previous office hour, I am opening this WIP PR for ongoing development. A few things to note:

1. The main algorithm implementation is nearly complete, with a few patches still pending.
2. The primary reference is the base paper ( The Self-Organizing Map, Teuvo Kohonen 1990 ), but note that it only states the batch algorithm where as this PR is regarding incr/lvq.
3. I will continue adding the remaining components of the package as they are completed.
