The Thrust Fancy Iterator Is a Very Useful Utility.

The thrust fancy iterators were completely borrowed from the boost fancy iterator. At first you'd think at they're not super like the utility of them. But once you start to reach for them, you start to notice that they like the constant iteration. Um, they are very, very useful utilities. There is one that i believe we don't have a counterpart for, and i don't know whether boost has it. Have you ever let at exist in thrust that does exain? I've never used it, but i've seen it in code reviews in rapi sowere. Solly yeats it, right? Yes.
