[boost] "Expect" exactness from your input

I added a file "iomanip_expect.hpp" to the Sandbox CVS. It provides manipulators to read an exact string from an input stream. This gives functionality from std::scanf that C++ I/O never had. Changed files "iomanip.hpp", "iomanip.html", and "iomanip_test.cpp" give additional tips. -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
