Porting boost.fusion to c++0x.

by Christopher Schmidt for Boost C++ Libraries

Since the c++0x puzzle begins to take shape and a lot of developers use compiler that support at least a subset of the c++0x language, new demands are made on boost.fusion. The main goal of this project is to follow these demands and update boost.fusion so c++0x developers can use this library intuitively without ugly workarounds or potentially wasted compile time.
