I've added some additional works to hopefully make it clearer that the
location of header directories and headers has indeed moved.

now is boost-root/libs/simple/include/boost/simple/simple.hpp
Note that the install procedure will install a logical link from
boost-root/boost/simple to boost-root/libs/simple/include/boost/simple
so that user includes like #include <boost/simple/simple.hpp> still
work. (Whether "logical link" is one link for the directory or one per
header, and whether symlinks, hard links, or file copies are used is
an implementation detail.)

A user wants to be able to tell a compiler "-Iboost-root" once, rather
than have to supply a path for each library. At the time, we didn't
want to bother with logical links.

(1) A unified directory structure for each library makes sense when
libraries live in their own public repos. (2) We want to preserve
existing user code, (3) we want to limit changes to directory
structure as much as possible.
