Hi folks,

A cross_iterator is to a zip_iterator as a cross_product is to a
dot_product.  For example, given two sequences { a, b }, { 1, 2 }, the
sequence of tuples generated by a cross_iterator would be { ( a, 1 ),
( b, 1 ), ( a, 2 ), ( b, 2 ) }.

I've put my implementation of cross_iterator in the sandbox
(cross_iterator.zip @ http://boost-sandbox.sourceforge.net/vault/). 
There's no documentation yet, but I've included a sample file that
demonstrates how to use the new iterator.

Please take a look and let me know what you think.
