// Details: MI common code class. Used to handle stream data from Stdin.
// Singleton class using the Visitor pattern. A driver using the interface
// provide can receive callbacks when a new line of data is received.
// Each line is determined by a carriage return.
// A singleton class.
// Gotchas: None.
// Authors: Illya Rudkin 10/02/2014.
