Update tutorials so that the name of the dimensionedScalar property is
no longer duplicated but optional dimensions are still provided and are
checked on read.

The templates include a stategy to simplify meshing with snappyHexMesh,
particularly to help generate an initial mesh quickly that can subsequently be
improved.  The templates are setup to enable rapid initial simulations, typically
with simpleFoam.  The initial templates cover simple inflow-outflow and closed
domains, including rotating geometry, and an example axisymmetric flow.  For
more details, consult the README file accompanying each template case.
The cases are located in $FOAM_ETC/templates

for more convenient case setup

See $FOAM_ETC/caseDicts/postProcessing/README for details

Note that in order to build and install ParaView-4.3.1 lines 653-656
must be removed or commented from file

ThirdParty-dev/ParaView-4.3.1/Qt/Components/CMakeLists.txt

after unpacking the ParaView-4.3.1 source-pack from KitWare.  This is
because the file ui_pqExportStateWizard.h referred to in the lines
653-656:

if(PARAVIEW_INSTALL_DEVELOPMENT_FILES)
  install(FILES "${CMAKE_CURRENT_BINARY_DIR}/ui_pqExportStateWizard.h"
          DESTINATION "${VTK_INSTALL_INCLUDE_DIR}")
endif()

does not exist and cannot be installed causing the build and
installation to fail.
