Function docstrings are missing

[AnshulMalik]

Issue type: Feature request (Infrastructure)

Description

Docstrings are used to explain what a module or function does, what are the parameters etc.
All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings.

Moreover it'll help new developers to get familiar with the code quickly.

One can pick functions one by one which he/she is familiar with, also this is a parent issue, so please don't say closes '1523'

I would like to work on this. It would speed up the process if you could direct me to a file that you want the docstrings added in or some resources to study about the workings of loklak (if not possible then I can try to understand it on my own). Or should I just pick any file of my choice and start working on it?

@palash25: You can proceed with your choice of package and add docstrings. Please also take a look at checkstyle issues for that file and correct them accordingly.
