 * HierarchyLevelAssociation is a class that orders Levels within a

 *
 * The relative ordering of DimensionDeployment classes optionally implies a
 * desired order of selection of DimensionDeployments, based on
 * implementation-specific considerations (e.g., optimized access of aggregate
 * data).
