To provide an answer to the question "For all Java projects, what is the distribution of commit log length? Is that in any way related to the number of issues of the project or to the distribution of issue length?"

We need to implement and test the features required to use Groundhog to answer the question in the title of the issue. We then have to use it to actually answer the question.

Hey @fernandocastor, could you explain what 'distribution of commit log length' means? Is just the number of commits?

BTW,

We should focus now on having #60 done and having this issue solved right after :)

What is the size of the commit messages? Another, maybe more interesting, measure would be the number of differences ('+'s and '-'s) between subsequent versions after each commit.
