  What are/is the differences between stlsoft::filter_iterator and

In Extended STL, volume 1 (of which you were a reviewer ;-) I observed that 
a filter iterator instance *must* always be given both bounding iterators of 
a given filterable range.

As I recall from during the preparation of the book, Boost's version does 
not do that, and is, therefore, suspect.

I may be misrecalling, and it may be that the Boost version has been 
"corrected" since. I'm certain of neither, and if someone wants to check and 
post the info here I'd be happy to be informed.

So essentially they should be functionally similar.
Of course I read the relevane XSTLv1 chapters :-), but I just wanted to make
sure that they were intended for the same purpose.
