Refactoring Essentials for Visual Studio

@vsrefactoring | vsrefactoringessentials.com

Refactoring Essentials started out as NR6Pack, and was part of the NRefactory 6 repository. In the course of
joint development, we made architectural tweaks that resulted in the two projects now being separate - which makes them easier to maintain and contribute to.

Please note that Refactoring Essentials is at its heart a PCL (portable class library), which means it is x-platform and not tied to Windows / Visual Studio.
