Subclassing XoWiki's Page Types

By refining XoWiki's page type, one can reuse its functionality.

Steps involved:

• Step 1: Define a new Page Type as a subtype of one of the XoWiki Page types
• Step 2: Define a Form for editing your values
• Step 3:  Provide custom rendering behavior for the page type, i.e. by introducing a type-specific method render.
