+Accessing original values
+-------------------------

+To access the saved state of the Task, use dict-like access using the
+``original`` attribute:
+
+    >>> t = Task(tw, description="tidy up")
+    >>> t.save()
+    >>> t['description'] = "tidy up the kitchen and bathroom"
+    >>> t['description']
+    "tidy up the kitchen and bathroom"
+    >>> t.original['description']
+    "tidy up"
+
+When you save the task, original values are refreshed to reflect the
+saved state of the task:
+
+    >>> t.save()
+    >>> t.original['description']
+    "tidy up the kitchen and bathroom"
