      public Iterator<T> concat(Iterator<? extends T> that)
      Description copied from interface: Iterator
      Returns a new Iterator that yields the elements of this iterator followed by all elements of the specified iterator.

      This method appends the elements from that to the end of this iterator, creating a concatenated sequence.

      Examples: 

       Iterator.of(1, 2).concat(Iterator.of(3, 4))  // yields 1, 2, 3, 4
 Iterator.empty().concat(Iterator.of(1, 2))   // yields 1, 2
 Iterator.of(1, 2).concat(Iterator.empty())   // yields 1, 2
      Parameters:
      that - the iterator whose elements should be appended
      Returns:
      a new iterator containing elements from both iterators
