Create an empty cache using the specified `evictionPolicy` and the specified `lowWatermark` and `highWatermark`. Optionally specify the `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `lowWatermark <= highWatermark`, `1 <= lowWatermark`, and `1 <= highWatermark`.
