Signature

def init_user_ns ( self )

Initialize all user-visible namespaces to their minimum defaults.

Certain history lists are also initialized here, as they effectively act as user namespaces.

All data structures here are only filled in, they are NOT reset by this method. If they were not empty before, data will simply be added to them.
