Exception: applyWallFunctionBoundaryConditions.C cannot split #include
directives.

Creates linear slope only from low and high elements around the sample
value, so rate will be discontinuous.  Would be better with higher
order gradient calculation.

This reverts commit 102f7970.

- aspect ratio and cellDeterminant do not use 3rd direction
- wedges are properly check for having opposite one

ENH: report line number for illegal words and for copyrights

- allows fixes before trying to push

- findAll() method returns a labelList of all matching names
- find() method returns the index to the first matching name

  For example, use a regex to specify alternative coordinate systems
  in porousZones
  (
      "cat1?(Back|Front)*"
      {
          coordinateSystem    "(cat1|system_10)";
          porosity    0.781;
          ...
      }
  )

- allows a regex to collect several cellZones.
  For example,
  (
      "cat1?(Back|Front)*"
      {
          coordinateSystem    system_10;
          porosity    0.781;
          ...
      }
  )

Adapted meshSearch and sampledTriSurfaceMesh to use it.
