Look over CursorPositions.bs2 and try to predict what the program will make the
LCD display do. Also try to predict the sequence and timing.
Enter, save, and run CursorPositions.bs2.
Compare the LCD display's behavior to your predictions.

Erasing Characters
You can always erase a character by placing the cursor where you want it and then sending
the space " " character to overwrite whatever might be there. This is why the text "Line 1 "
has a space after the "1" character, to erase the characters to its right as the text moves left.
