Wrote SegmentPackageWrangler.interpret_make_module() tests.

Here's what SegmentPackageWrangler (mmi) looks like now:

    Red Example Score (2013) - segments

       1: segment 01
       2: segment 02
       3: segment 03

          segments - copy (cp)
          segments - new (new)
          segments - remove (rm)
          segments - rename (ren)

    > mmi
