Adding Gitective [1] as a dependency and creating the class that will be

responsible for the local Git repository analysis within Groundhog.

Starting with non-parameterized commit extraction and extraction of commits from a given user.

Nothing finished just yet. Code in main package only present for current
debugging and testing purposes, once the commit message extraction is
done it will be moved to the groundhog-case-study [2] project.

Related to #55 and #60
