 Hi Nicolas,

 I started to review this. I currently have only the following interface
 remark: id there a reason why you need to pass a tuple for parameter
 {{{facade}}} whereas for {{{category}}} you can pass either a category or
 a
 tuple ? For example, why do you force the user to write
 {{{
 Parent.__init__(self, facade = (IntegerRing(), ), category = Sets())
 }}}
 instead of
 {{{
 Parent.__init__(self, facade = IntegerRing(), category = Sets())
 }}}
