Maintain uniform coding styles

[ironmaniiith]

I see a lot of variation in coding style being followed by all the contributors. It's good to fix to a single coding style and let's all follow the same. (Bracketing styles, putting semicolons, spacing between assignment operations, variable declarations, constant declarations etc. need to follow same pattern throught)

Please put up a doc for the same

Was gonna do a cleanup commit later and enforce a stricter coding style, since currently many of them are beginners to open source (they have difficulties handling tab/space errors right now)

Can we set up codacy or some similar CI?
