Contribution summary

[acavalla]

Hi all @rawnakhoque @psomdeb25 @fangwuwang

We also have to produce a 'contribution summary'. I've written my section and uploaded it into the main repo. I left the instructions of how to write it in there, so maybe leave those there until the last person has finished their part. This part is due tomorrow night at 23:59 I believe.

Thanks!
Annie

Please put all your R codes and packages/tools, method-related information in the new Methods folder. Think it is more convenient to throw all your codes here and link to the markdown file.
