Create an object pool that uses the specified `objectCreator` (encapsulating the construction of objects) to create objects. The client must ensure that `objectCreator(buf, alloc)` creates an object at memory location `buf` using `alloc` to supply memory. When the pool is depleted, it will grow capacity according to the optionally specified `growBy` value. If `growBy` is positive, the pool replenishes itself with at least `growBy` new objects. If `growBy` is negative, the amount of increase begins at `‐growBy` and grows geometrically up to an implementation‐defined maximum. When objects are returned to the pool, the default value of RESETTER is invoked with a pointer to the returned object to restore the object to a reusable state. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `0 != growBy`.
