Comment:

 I confirm that I made a design error yesterday while making the change to
 the strided adaptor. The code I committed yesterday did not support
 ForwardRange or SinglePassRange concepts. Additionally it did not perform
 as we wanted. It was setting the last iterator in the range to be the last
 valid iterator on a stride boundary.

 To correct this I have added offset and max_offset information into the
 strided_iterator. This is required so that we can use the offset to go
 past the end of the range while avoiding advancing the underlying iterator
 beyond valid values. This change additionally corrects a defect with
 interoperability of strided iterators.
