editing the respective settings files.

- foamEtcFile is used to find the files, thus follows the standard
  ~OpenFOAM/fileName expansion mechanism.

BUG: engridFoam had $WM_ARCH instead of $WM_ARCH$WM_COMPILER

- avoids odd side effects that can occur when a wordList is treated as
  a list of regex patterns

- this allows more direct use by c-shell

- the 'make install' target from ParaView now installs all of the
  includes necessary for compiling plugins.

ENH: move plugin to paraview-$ParaView_MAJOR

(less memory)

The optional 'average' switch causes use of the average-of-pointvalues
instead of the original volField.

ENH: use face::trianglesQuads() method for PV3FoamReader as well.
- this avoids missing faces (and weird cells) in the decomposed polyhedra.

Create a new case from a template for particular applications

Is more convergent&stable than switching.

The dummyThirdParty tree builds libraries which are drop-in
(but non-functional) versions of some thirdparty libraries. This will
make it easier to ship binary versions without having to ship thirdparty packs.

It uses mpicc to find out where the installed libraries are.

This signals that we are using the system installed openmpi version.
