Began implementation of io redirection.
Created a function Redirect that will handle io redirection on
	commands.
The Redirect function is currently able to isolate a command and its
    arguments from a line with input output redirection.
Piping still does not function correctly.
IO redirection in a non piped command works.
Piping two non io redirection commands works but...
The commands will execute and display the result, but then will
    fail to reach the input prompt again.
Only tested on two commands.
