Design:

1. The hint prompt is displayed after the secrete word is successfully stored.
2. The hint word is stored and displayed every time the dashed guess space is
rendered. Example:

- - - - - - a -
Hint: My Hint

> Enter a letter: h

h - - - - - a -
Hint: My Hint

------------------------------------

Function reuse:
readLine() can be used to retrieve a line of input from the user
