mGraphFile is a data member of type boost:filesystem::path, which isn't 
(as I understand) handled natively by Boost Serialization.  I could define

     template<class Archive>
     void serialize(Archive& ar, boost::filesystem::path& p,
                    const unsigned int version);

but it is needed in only one place.

Below is an excerpt from an inline serialization function that I'm 
already using.  While it has a redundant step not needed for loading and 
a different redundant step not needed for storing, it would seem to do 
what I need.  (The minor inefficiency of the redundant statements is of 
no concern here.)

         ...
         std::string str = mGraphFile.string(); // redundant if loading
         ar & BOOST_SERIALIZATION_NVP(str);
         mGraphFile = str;                      // redundant if saving
         ...

Can anyone tell me if this will work, or do I need to implement the 
serialize() function?
