Adjust config foundation merge

Rationalize config files, foamy build, tutorials.

See merge request !63

Note: should be using the result of the parent::read(dict) when
deciding whether to read local entries...

- The zero directory is incomplete, skip these entries.

- the function objects are from issue #224 and issue #235

- CGAL itself includes its library dependencies, we only need to
  provide the -L... option to the proper ThirdParty locations.

  Should help improve general build robustness.

Merge branch 'merge-foundation' of develop.openfoam.com:Development/OpenFOAM-plus into merge-foundation

- instead we use the CGAL settings directly since they have the
  same option of (version | system | none)

- may wish to review this again in the future.

blockMesh -help

Usage: blockMesh [OPTIONS]
options:
  -blockTopology    write block edges and centres as .obj files
  -case <dir>       specify alternate case directory, default is the cwd
  -dict <file>      specify alternative dictionary for the blockMesh description
  -noFunctionObjects
                    do not execute functionObjects
  -region <name>    specify alternative mesh region
  -srcDoc           display source code in browser
  -doc              display application documentation in browser
  -help             print the usage

Block description

  For a given block, the correspondence between the ordering of
  vertex labels and face labels is shown below.
  For vertex numbering in the sequence 0 to 7 (block, centre):
    faces 0 (f0) and 1 are left and right, respectively;
    faces 2 and 3 are bottom and top;
    and faces 4 and 5 are front the back:

           4 ---- 5
      f3   |\     |\   f5
      |    | 7 ---- 6   \
      |    0 |--- 1 |    \
      |     \|     \|    f4
      f2     3 ---- 2

            f0 ----- f1

   1. Spaced ending of multi-level template parameters are not allowed, such as:

       List<List<scalar> >

     which instead should be:

       List<List<scalar>>

   2. The use of the 'NULL' macro should be replaced by 'nullptr'

fvPatchFields: Constructors from dictionary now call the corresponding constructor of the fvPatchField base-class
to ensure 'patchType' is set as specified.

Required substantial change to the organization of the reading of the
'value' entry requiring careful testing and there may be some residual
issues remaining.  Please report any problems with the reading and
initialization of patch fields.

e.g. for the cavity tutorial the moving wall patch can be specified in
terms of the block vertices as before:

boundary
(
    movingWall
    {
        type wall;
        faces
        (
            (3 7 6 2)
        );
    }
    .
    .
    .

or the new specification of the face as block 0, block face 3:

boundary
(
    movingWall
    {
        type wall;
        faces
        (
            (0 3)
        );
    }

- Similar to ensight converters (issue #240),
  improve speed for detection of lagrangian clouds.

- provide a -noLagrangian option for symmetry

- Less looping when detecting lagrangian clouds and their fields.

- Avoid using Time::setTime() and IOobjectList in tight loops.
  They both kill performance immensely.

ENH: provide a -noLagrangian option to foamToEnsight and foamToEnsightParts
for even more control.

- More informative than a horizonal line, can help when debugging.

STYLE: remove unused write field methods from ensightParts

- The new field needs initialization with a dimensioned<Type> not just
  the dimensionSet.

- The new field was also incorrectly being registered, which could
  cause issues later.

- affects foamToEnsightParts, sampled surfaces

- Use ensightPTraits mechanism throughout to avoid this issue
