node_configure_fields($type)

Manage the field(s) for a node type.

Currently, the node module manages a single Field API field, 'body'. If $type->has_body is true, this function ensures the 'body' field exists and creates an instance of it for the bundle $type->type (e.g. 'page', 'story', ...). If $type->has_body is false, this function removes the instance (if it exists) for the 'body' field on $type->type.
