 * add examples (and credits) from @alanjfs :)
 
 WIP:
-* make ::page/::offset (sparse_set/storage) publicly available, decouple storage iterator from allocator
 * fast-contains for sparse sets (low prio but nice-to-have)
 * runtime components (registry), runtime events (dispatcher/emitter), runtime context variables ...
 * runtime_view/registry, remove reference to basic_sparse_set<E>
 * make pools available (registry/view/group), review operator| for views, make views accept registry to ctor
 * make view.lead() or similar available to return leading pool (useful for mt)
 * dedicated entity storage, in-place O(1) release/destroy for non-orphaned entities, out-of-sync model
+* review storage::release_memory (we can't really call ::clear now that it honors the mode)
 * custom allocators all over
