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