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