+Module Name:
+
+ ConsoleIn.c
+
+Abstract:
+
+ Console based on Win32 APIs.
+
+ This file attaches a SimpleTextIn protocol to a previously open window.
+
+ The constructor for this protocol depends on an open window. Currently
+ the SimpleTextOut protocol creates a window when it's constructor is called.
+ Thus this code must run after the constructor for the SimpleTextOut
+ protocol
