/**
 * Inject profile data into a Model, using the profile as the dominant data source, and
 * persisting results of the injection in the Model.
 *
 * This will look similar to the ModelUtils/DefaultModelInheritanceAssembler code, but
 * they are distinct. In model inheritance, the child provides data dominance AND persists
 * the results of the merge...sort of a 'merge-out' system.
 *
 * In this system, the profile is dominant, but the model receives the merge result...sort
 * of a 'merge-in' system. The two pieces of code look like they could be combined with a
 * set of flags to determine which direction to merge 'to', but there are enough differences
 * in the code to justify the extra code involved with separating them, in order to simplify
 * the logic.
