Title: Git relational structure refactor

This PR fulfills @gvwilson 's request to promote the discussion of relational git structure to an intermediate lesson. Also, some of the jargon from this discussion was not removed from the novice lesson where it originally resided; this PR also cleans up the novice lesson WRT avoiding undefined terminology.
