## Detailed Description

Range iterator for pointwise minus of a range iterator.

This iterator in effect changes the order of how ranges are iterated: the first range of the input iterator defines the last range of the Minus iterator. Upon initialization all ranges of the input iterator are stored which later allows iteration in inverse direction.
