c++11 standard overview

Sure they have added a few things, lambdas, auto, shared ptrs, rvalue references, but if the spent the time they used on their second hat (^) c++ extension, aka c++/cx and added stuff like variadic templates, data member initializers, etc... that would have been a lot better.

Also why not make a clean library c++ library for WinRT instead of some non-standard proprietary c++ extension.
