[GSoC] Update about Blog

Hello Git community,

I am Jaydeep Das and my proposal[1] got accepted in GSoC(almost been 3 weeks now).
I am already in contact with my mentors Christian and Hariom. So, I will be posting weekly blogs
regarding my progress and difficulties here[2]. I have already posted 2 blogs and I am actually a bit
behind the schedule on blog posting the 3rd blog.

In the last blog, I tried to understand(and explain) the basic working of git-for-each-ref. Although, it was
difficult to grasp at first, Hariom's blog[3] was of great help.

Currently, I am going through pretty.c trying to understand it little bit. Mostly be trying to eliminate duplicate/
redundant code.
