Create an empty `StripedUnorderedContainerImpl` object, a fully thread‐safe hash map where access is divided into "stripes" (a group of buckets protected by a reader‐write mutex). Optionally specify `numInitialBuckets` and `numStripes` which define the minimum number of buckets and the (fixed) number of stripes in this map. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The hash map has rehash enabled.
