027 * A test which demonstrates maven's recursive inheritance where
028 * a distinct value is taken from each parent contributing to the
029 * the final model of the project being assembled. There is no
030 * overriding going on amongst the models being used in this test:
031 * each model in the lineage is providing a value that is not present
032 * anywhere else in the lineage. We are just making sure that values
033 * down in the lineage are bubbling up where they should.
