+		A fast and densely stored hashmap and hashset based on robin-hood
+		backward shift deletion.
+		The classes ankerl::unordered_dense::map and
+		ankerl::unordered_dense::set are (almost) drop-in replacements of
+		std::unordered_map and std::unordered_set. While they don't have as
+		strong iterator / reference stability guaranties, they are typically
+		much faster.
