Create an in‐place queue with sufficient initial capacity to accommodate up to the specified `numElements` values without subsequent reallocation. A valid reference returned by the `operator[]` method is guaranteed to remain valid unless the value returned by the `length` method exceeds `numElements` (which would potentially cause a reallocation). 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 <= numElements`.
