Description

Should we implement a class for list/vector of RingElem, all guaranteed to be in hte same ring? (a bit like PPVector)
Nice thing would be that the empty list would know which ring it belongs to.
Think about it!

I am postponing, but also increasing priority.

I think this idea will be quite useful, but we need more time to think about it and make a good impl.
Ideally, next time Anna and I can meet somewhere (somewhen).

NOTE it might also be nice to have VectorVectorRingElem for creating matrices.

Yes! We really should implement this, and preferably soon.
Maybe we can also include an auto conversion to vector<RingElem> which should help ensure compatibility: e.g. might be useful for printing?
