Added traits:

is_incrementable.hpp: checks whether ++x is well-formed

   pointee.hpp: value_type of iterators or smart pointers

   indirect_reference.hpp: reference type of iterators or smart pointers

indirect_iterator.hpp
indirect_iterator_member_types.cpp

   Use pointee/indirect_reference to select value/reference type.

iterator_concepts.hpp: Fixed interoperable test.  Hardly tests enough, but it's a start

minimum_category.hpp: Better error messages for vc6

indirect_iterator_test.cpp: Workarounds for compilers without SFINAE

static_assert_same.hpp: Informative error reports; added a macro.

zip_iterator_test.hpp: Added missing #include

Jamfile: made zip_iterator test pass with vc6/stlport
