What to do
For this exercise, write a program that
simply echoes every line the user enters until the enter a line that
is just the word "quit" at which point the program should exit.

ready for input.
You should use input.nextLine() to read an entire input
line, where input is a reference to
a Scanner object.
Here is a sample execution. The user input is in bold.
