LongLongDoubleHashMap (SystemDS 2.0.0 API)

```
public class LongLongDoubleHashMap
extends Object
```
This native long long - double hashmap is specifically designed for ctable operations which only require addvalue - extract semantics. In contrast to a default hashmap the native representation allows us to be more memory-efficient which is important for large maps in order to keep data in the caches and prevent high-latency random memory access.
