An interface that gives a better control over the load factor and the minimum capacity for HashMap. The size of `HashMap<K, V>` is now 64 bytes by default on a 64-bit platform (or at least 40 bytes, that is 3 words less, with FNV and without minimum capacity) Unanswered questions about `ResizePolicy` * should it control the `INITIAL_CAPACITY`? * should it fully control the resizing behavior? Even though the capacity always changes by a factor of 2. * is caching `grow_at` desirable? special thanks to @eddyb and @pnkfelix
