New description:
Implementation of a set (using the category framework) from a function
that returns an iterator as in
{{{
sage: from sage.sets.set_from_iterator import EnumeratedSetFromIterator
sage: E = EnumeratedSetFromIterator(graphs)
{Graph on 0 vertices, Graph on 1 vertex, Graph on 2 vertices, Graph on 2
vertices, Graph on 3 vertices, Graph on 3 vertices, ...}
}}}
Note that in order to be able to pickle, we do not build directly a set
from an iterator.
A previous implementation in sage-combinat was
CombinatorialClassFromIterator (in sage.combinat.combinat) which is now
deprecated.
The patch depends on #12653 which allows to initialize a graph from a
dictionnary of iterables.
