+<!-- This file contains Debugger Visualizers for the FC library.  It's hard to navigate the
+	 FC objects in a debugger because the tricks used in classes like fc::fwd require manual
+	 casting to view the underlying objects in the debugger.  This file tells the Visual 
+	 Studio debugger how to see through these tricks and traverse the classes naturally.
+	 
+     To install, drop this file in your My Documents\Visual Studio 2012\Visualizers directory 
+	 
+     In addition, consider grabbing the .natvis files from the C++ Debugger Visualizers
+	 project here to improve display of boost objects:
+		https://github.com/KindDragon/CPPDebuggerVisualizers#c-debugger-visualizers-
