-------------------------------------------+--------------------------------
Changes (by novoselt):
* work_issues: => sublattice duals and action
Comment:
Update: 1 and 2 are easy and done, 3 is in principle also easy and done,
but it does not yet work due to sublattice handling. So I am working on
improving it. Ideally I want to be able to do in sublattices and quotient
lattices everything that can be done in the ambient ones. Several steps in
this direction were already done, this patch will make a few more ;-)
