Monthly code flow - lines changed (additions, deletions)

[mihneadb]

Should find out for every month how many additons and deletions are made.

This info has to be gathered from the "commitevent" documents, similar to the way described in issue #13. The "stats" attribute in these documents has all the info we need.

Github's Code Frequency offers this analysis. Checking to see if there's a providing API It does through Statistics API. As this dashboard will eventually support any type of data source I wouldn't focus on this at this point.

Felt the need to move this to an Icebox, Backlog, milestone. There's none, so spending 15min to see how other people are doing this. not conclusive, 90% don't use milestones to group their issues, it's more of a free for all type of deal. Until more people feel the need of a milestone, leaving it as is.
