    Steps:
    - Setup MainActivity with a TextView to edit, and a button to trigger the dialog box.
    - Create a layout XML file for the dialog's appearance
    - Create a Java class inheriting from AppCompatDialogFragment to build the AlertDialog
    - Show the AlertDialog from main using a fragment manager.
    - Add a cancel button
    - Call .finish() on the parent activity to close it.
