+"""Simple base-classes for extensions and filters.
+
+None of the filter and extension functions are considered 'optional' by the
+framework.  These base-classes provide simple implementations for the
+Initialize and Terminate functions, allowing you to omit them,
+
+It is not necessary to use these base-classes - but if you don't, you
+must ensure each of the required methods are implemented.
