+Description
+    Polynomial container data entry for scalars. Items are stored in a list of
+    Tuple2's. Data is input in the form, e.g. for an entry <entryName> that
+    describes y = x^2 + 2x^3
+
+    @verbatim
+        <entryName>   polynomial
+        (
+            (1    2)
+            (2    3)
+        );
