     //   Once the user alters the default text, the textbox will no longer be cleared.
     // In addition, it sets the text box text color to black.
     // If the user exits the text box, the default text will be reentered into the textbox.
     // In addition, it sets the text box text color to gray.
     //
     // The textbox argument is the ID of the textbox.
     // The text argument is the default text of the textbox.
