         For each cell with only one point on wall the same is done except now it

-Note
-
-    correct() : for now does complete recalculation. (which usually is
-    ok since mesh is smoothed). However for topology change where geometry
-    in most of domain does not change you could think of starting from the
-    old cell values. Tried but not done since:
-    - meshWave would have to be called with old cellInfo.
-      This is List\<wallInfo\> of nCells.
-    - cannot construct from distance (y_) only since we don't know a value
-      for origin_. (origin_ = GREAT already used to denote illegal value.)
-    - so we would have to store a List\<wallInfo\> which unfortunately does
-      not get resized/mapped automatically upon mesh changes.
