--------------------------+-------------------------------------------------
There is a pickle error with the nested class RauzyDiagram.Path in
sage.combinat.iet.template
{{{
sage: p = iet.Permutation('a b c','c b a')
sage: r = p.rauzy_diagram()
sage: g = r.path(p, 't', 'b')
sage: dumps(g)
PicklingError Traceback(most recent call last)
...
PicklingError: Can't pickle <class 'sage.combinat.iet.labelled.Path'>:
attribute lookup sage.combinat.iet.labelled.Path failed
}}}
A __metaclass__ must be defined for RauzyDiagram.
