+
+Description
+    Calculation of distance to nearest patch for all cells and boundary.
+    Uses meshWave to do actual calculation.
+
+    Distance correction:
+
+    if correctWalls = true:
+    For each cell with face on wall calculate the true nearest point
+    (by triangle decomposition) on that face and do the same for that face's
+    pointNeighbours. This will find the true nearest distance in almost all
+    cases. Only very skewed cells or cells close to another wall might be
+    missed.
+
+    For each cell with only one point on wall the same is done except now it
+    takes the pointFaces() of the wall point to look for the nearest point.
+
+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.
