+    Multline Element - Input Justification
+
+    The justification of text for the Multiline element defaults to Left Justified
+    Because of the way tkinter's widget works, setting the justification when creating the element
+    is not enough to provide the correct justification.
+
+    The demo shows you the technique to achieve justified input
+
+    Key points:
+        * Enable events on the multiline
+        * Add 2 lines of code to your event loop
+            * If get mline element event
+                * Set the contents of the multline to be the correct justificaiton
