#9677: Sage Sets don't implement genuine comparison

--------------------------------+-------------------------------------------
Right now there is either equals, or less than. If `a != b`, then we get
`a < b` but not `b > a`:
{{{
sage: a = Set([1])
sage: b = Set([])
sage: a == b
False
sage: a < b
True
sage: b > a
False
}}}
