- 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.

ENH: upgrade to env. variable to ensight9 (current version)

This appears to be a long-standing bug!?, since it was also in the
paraview-2 reader.
