      public static boolean isHeatmapFacet(NamedList<?> potentialHeatmapValues)
      A NamedList is a proper "heatmap" response if it contains all expected properties

      We try to be rather strict in determining whether potentialHeatmapValues is a "heatmap". Users can name subfacets arbitrarily, so having some names match those expected in a "heatmap" response could just be coincidence.

      Heatmap facets do not support subfacets.
