/*
CompSci 101 - Keyboard Class
============================
This class is used for input from the keyboard.
You do not need to understand the details of this class.
To use this class, put it in the same directory as the source
file for your program, and include the statement:
  String input = Keyboard.readInput();
in your program.  This will assign whatever is typed at the
keyboard to the input variable.
