[boost] Parallel/MPI: Renaming the library directories?

From: Doug Gregor (dgregor_at_[hidden])

Back when we started writing the Message Passing library, we decided  
to put it into the "parallel" subdirectory (then the "mpi" sub-sub- 
directory), because we were hoping that "parallel" could become a top- 
level categorization for various parallel-programming libraries...  
threads, mpi, shared memory, etc. That may happen some day (when we  
manage to break Boost into pieces), but for now it's just a pain.  
Users need to using the longish namespace "boost::parallel::mpi",  
file names "boost/parallel/mpi", and run bjam with "bjam --with- 
parallel" (rather than "--with-mpi").

So, unless I hear screams, I'm going to move libs/parallel into libs/ 
mpi, boost/parallel into boost/mpi, and simplify its underlying  
directory structure a bit. When the time comes to split up Boost, and  
if it involves deeper namespaces, we'll make the change again then.  
For now, simpler is better.

        Cheers,
        Doug
