[boost] [utility] What happened to OptionalPointee/compare_pointees?

1) OptionalPointee/compare_pointees reside here: libs/utility/OptionalPointee.html, but there's no way to navigate to it from here: libs/utility/ or here: libs/utility/utility.htm 2) IMO, compare_pointees should have stand alone documentation, and be grouped with pointee and indirect_reference. 3) pointee and indirect_reference are not iterator specific, therefore they shouldn't reside under iterator's documentation. IMO, compare_pointees, pointee and indirect_reference should all reside under a pointee utilities section. Thanks.
