It does the same thing as InitializeClass(), i.e. add security
declarations, a meta type etc to classes.

For Archetypes, it's taken care of you by registerType(), so you don't
need it. Dexterity does it for you as well. You may need it in some
cases, like when building PAS plugins or persistent tools.
