[boost] [New Feature Suggestion] Fast RTTI Implementation

Hello there. Let me introduce the fast rtti system. Many other library and system(ex. game engines) has there own rtti system. But normally their rtti system consume Big O(n) for dynamic casting another type. So, I implemented fast rtti Big O(1) time consuming rtti system. I used bit signature for class inhertance hierarchy expression. Thanks for reviewing my mail and source code
