implements java.io.Serializable, java.lang.Cloneable
```
A type-specific red-black tree map with a fast, small-footprint implementation.
The iterators provided by the views of this class are type-specific bidirectional iterators. Moreover, the iterator returned by iterator() can be safely cast to a type-specific list iterator.
