[boost] Identification library preliminary version

Hello all, I've uploaded a preliminary version of my type identification library into the vault (identification-v.01.zip) It's the current implementation of my type debugging facility that provides a simple function and class to build at run-time a human readable string containing the name of its type arguments. Identification supports a simple way to register user-defined types into itself. Samples and documentation are provided. It has been tested on g++ v4+ (both linux and windows) and on MSVC 2008 with equal success. Test on other platform and compiler are welcome as well as general comments on the interface or implementation choices. Thanks in advance.
