Domain update by iterator

Views can be both updated by range and value iterators. Value iterators do not need to be strict in that the same value is allowed to occur more than once in the iterated sequence.

The argument depends must be true, if the iterator passed as argument depends on the view on which the operation is invoked. In this case, the view is only updated after the iterator has been consumed. Otherwise, the domain might be updated concurrently while following the iterator.
