New description:
The patch, under development on the sage-combinat patch server, creates
the category {{{GradedEnumeratedSets}}}. It also:
- Puts Partitions() into this category
- Implements {{{WeightedIntegerVectors(weights)}}} (whose graded
compontents are the previously existing {{{WeightedIntegerVectors(n,
weights)}}}).
- Add a {{{category}}} optional argument to
{{{DisjointUnionOfEnumeratedSets.__init__}}}.
