1. Create a library of command functions for the LCD to do the following
   1. Clear display
   2. Turn cursor on/off
   3. Turn blinking on/off
   4. Print to a particular line and column
   5. Move cursor right n-spaces
   6. Move cursor left n-spaces
   7. Scroll display right n-spaces
   8. Scroll display left n-spaces
   9. Initialize the LCD
   10. Write a message to the LCD

2. Write a program so that the LCD mirrors the PuTTY terminal window as closely as possible and special inputs can be used to control the LCD display. For example, pressing the backspace key should make the cursor move backwards and delete one character, while pressing a non-display character, such as CTRL-C, in the PuTTY window will clear the LCD display.
