UjoIterator (Ujorm 1.73

java.lang.Object
- org.ujorm.core.UjoIterator<T>

All Implemented Interfaces:

Closeable, AutoCloseable, Iterable<T>, Iterator<T>
```
public abstract class UjoIterator<T>
extends Object
implements Iterable<T>, Iterator<T>, Closeable
```
Ujo iterator have got some extended functions:
- iterator can provide optionally a count of items by a count() method
- iterator can be used in generic loop syntax for( : )
- iterator can create a List object
