[boost] smart_ptr suggestion: smart_ptr.hpp should include weak_ptr.hpp, etc.

For convenience, logical continuity, and consistency with other Boost 
libraries, you should be able to include all the smart_ptr pieces with

     #include <boost/smart_ptr.hpp>

Currently, only 4 are included:

     #include <boost/scoped_ptr.hpp>
     #include <boost/scoped_array.hpp>
     #include <boost/shared_ptr.hpp>
     #include <boost/shared_array.hpp>

Missing are:

     #include <boost/weak_ptr.hpp>
     #include <boost/intrusive_ptr.hpp>
     #include <boost/enable_shared_from_this.hpp>

If the idea was to leave out rarely-used, specialized pieces, in order 
to cut down on extraneous compile time, then I'd suggest that 
weak_ptr.hpp needs to be included in smart_ptr.hpp -- it seems to me to 
be one of the essential, common components of the smart_ptr system.

It took me awhile to debug my first test program, because I couldn't 
figure out how to get a weak_ptr to compile -- turned out I didn't have 
weak_ptr.hpp included, which was very puzzling to me, since I had 
included smart_ptr.hpp (which is why it took so long for me to figure it 
out...)
