History for BoboTraverse

??changed:
-
BoboTraverse is just one of the many functions that get called when 
ZPublisher is working out which object to Publish. 'ZPublisher/BaseRequest.py'.

Publishing steps:

   1. Path is broken down into a list eg a/b/c becomes ['c','b','a']
      and stored as request['TraversalRequestNameStack']

   2. The current objects __before_publishing_traverse__ method is called,
      and return values are ignored::
     
      __before_publishing_traverse__(object, request)

      See Shared/DC/Scripts/Bindings.py for an example of __before_publishing_traverse__. 
      There, the excess URL bits are stripped off, and assigned to traverse_subpath::

      path = request['TraversalRequestNameStack']
      subpath = path[:]
      path = [:]
      subpath.reverse()
      request.set('traverse_subpath', subpath)
     
   3. BoboTraverse is then called. There are two possible types
      of return values ::

      subobject = __bobo_traverse__(request, entryname)
      parents, parents, ..., parents, object, subobject = __bobo_traverse__(request, entryname)
