#2 - C implementation of command server API

The second week got me introduced to the project. I started the week
with a brainstorming session on how to manage the data structure
within my project.
Then I created a header file where the function signatures are found.
This was a good point to start and I got some review and some good
advice concerning it.
In the second part of the week I implemented the “level 0” of the API.
I established a connection with the command server, through the pipes,
and then I changed some messages with the server. This was done by
passing a raw command after which I got unparsed results which were
printed on the standard output.
After my first commit, I received lots of reviews from Giovanni. I am
aware that there are some problems but I will try to solve them so I
can be ready to go to the next level.

#1 - C implementation of command server API

Hi, my name is Iulian Stana, and this summer I will participate at
GSoC ( Google Summer of Code), where I will implement an API for the
mercurial engine.

The first week, passed already. I would say that it was an
accommodation week, during which I met my future mentors, Pierre-Yves and
Giovanni and the community of the mercurial. We discussed about my
project and about some organizational stuff.

I created a plan, and I tried to discuss it with the community. I got
some useful advices, and I am confident that I am prepared for the
project. I also created a timeline that I will follow which will help
me to meet the deadlines. I also created some wiki pages on mercurial

where people can watch my progression :

- C-Hglib

- Mercurial-IulianStana

and also a repo where my code will be posted:

-  C-hglib repo
