+ * This exception is thrown by the container classes in Gats when one of the
+ * casting helper functions is used to extract a value.  In those cases,
+ * in java we could still potentially return a null (at least if we were
+ * using object types).  This has a couple of advantages when working with
+ * non-object types, and maintains compatability with other implementations
+ * of the Gats library.
