New description:
1) The library for iet is moved from sage.combinat.iet to
sage.dynamics.interval_exchanges which seems more natural.
2) The old version for iet uses two kinds of datatype for reduced and
labeled versions. The new implementation makes them coherent.
3) As a by product of 2), the following behavior is corrected
{{{
sage: p = iet.Permutation('a b','b a')
sage: q = iet.Permutation('b a','a b')
sage: p == q
True
}}}

Comment (by chapoton):
ok, here it is. It seems that my doc framework is now completely broken (I
have by mistake removed the output directory and now docbuild complains a
lot about intersphinx and missing files), so I do not know if the doc is
ok.
for the bot:
