Extension:Annotator/Prototyping inline comments

This is a proposal for Google Summer Of Code 2013 for the project [|Prototyping inline comments] which will be mentored by MattFlaschen.

About the Project: Protoyping inline comments
This will be an extension where the user after landing to a wiki article can select few lines or part of a line and make an inline comment and the others can also reply to it. Users can make useful comments regarding specific part of articles, which will be a part of collaborative work. It will be something like co-ment and stet.

Plans and estimated timeline
My basic plan and estimated timeline for the project during three months of internship after discussing with my mentor are: (timeline may change a little during the project)

Applicant background
Hi, I am Richa Jain, interested in programming since school time and a FOSS enthusiast. I have started working for wikimedia since January and understanding the concepts of mediawiki core, taking active participation on irc chats and fixing bugs made me learn a lot.

Before this, things have worked on
 * Made an app 'Experiences at IIT R' for the IIT Roorkee students to share experience about their college life (involved php, jquery, mysql)
 * Contributed to the team page of SDSLabs.
 * Contributed to the hubot script (involved coffescript).
 * Made the website for Srishti (hobbies club fest) of our college.

Contribution to mediawiki
I have fixed some bugs of mediawiki core and Extension:UploadWizard.
