-    @discussion The expression view is the view that displays the contents of an
-                expression storage. Normally you should not call the setter of
-                this property. It is automatically assigned when the <code>@link
-                //apple_ref/occ/instp/MPExpressionView/expressionStorage@/link</code>
-                property of the respective <code>@link
-                //apple_ref/occ/cl/MPExpressionView@/link</code> instance is set.
- 
-                When this property is set the receiver assumes that the
-                displaying expression view has changed (regardless of wether the
-                actual value of the property changed or not). It then adapts to
-                the properties of the new expression view and discards the
-                current root layout.
