[boost] [announce] Dynamic object factory v3

Yet another object factory announce! Sorry to announce another version, but I think "this is the last one" (tm) ;-) Small, easy to read, self-contained, feature complete, compiler friendly, and really really nice (at least for my coding style taste). I spent a lot of time polishing this toy. IMHO could be an example of C++ template programming for beginners/intermediate users. Interested people could find it in boost vault under the name factory_24_2_08.zip, of course any feedback is welcomed. Thanks for your attention Marco
