Module Name:
ConsoleIn.c
Abstract:
Console based on Posix 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
