Recursive insertion sort

[shrabian]

Hey,

I'm new to github and thought this repo would be a good opportunity to get familiar and contribute a simple algorithm. I noticed the sorts folder is lacking a recursive implementation of the insertion sort. Is it OK if I add one?

By any means go ahead, Do have a look at CONTRIBUTING.md, and reach out in case of any further queries. happy coding :)

Hey,
I've already implemented this algorithm and it has been merged into master. Sorry for not closing this sooner.
