Wave propagation of information through grid. Every iteration information goes through one layer of edges.
Templated on information that is transferred.
Handles parallel and cyclics. Only parallel reasonably tested. Cyclics hardly tested.
Note: whether to propagate depends on the return value of Type::update which returns true (i.e. propagate) if the value changes by more than a certain tolerance.
Note: parallel is done in two steps:
Note: cyclics is with offset in patchface as well. Patch is divided into two sub patches and the point-point addressing is never explicitly calculated but instead use is made of the face-face correspondence. (it probably is more efficient to calculate a point-point correspondence at the start and then reuse this; task to be done)
