Egg Review starts today March 31st

The review of the Egg library by   Shunsuke Sogame  starts today.The library is concerned with the
implementation and adaptation of function objects. As function objects are everywhere in Boost and C++,
I hope to see plenty of discussion and votes during the review.

Introduction:
    It is not so easy to define Function Objects
    especially if you want to support Boost.ResultOf and Boost.Lambda.
    Therefore, as Boost provides iterator_facade and iterator adaptors,
    Egg provides function_facade and function adaptors.

Egg provides the following features:

    * Workaround for the Forwarding Problem
        http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1385.htm

    * Helpers to build Function Objects:
        * egg::function and egg::function_facade provides the way to
          build Function Objects which supports Boost.ResultOf and Lambda.

    * Function Objects Adaptors(in other words, higher-order functions):
        * egg::curryN supports the currying.
        * egg::pipable emulates extension methods(C#).
        * egg::fuse/unfuse emulates variadic functions.
        * egg::nestN represents nested lambda expressions.
        * etc...
