// <motivation>
// Since operations on Lattices can take a while, it can be useful
// to show the progress. However, making module Lattices dependent on
// the class ProgressMeter sounded bad. This abstract class serves
// as a bridge between the Lattice module and the ProgressMeter class
// (or any other class showing the progress).
