      ENH: add wall-function blending treatments · 07a5babd
      Kutalmis Bercin authored
          Please see the Extended Code Guide and header files for the details.
      
          ENH: add wall-function blending treatments to epsilonWallFunc
               adds `stepwise`, `max`, `binomial`, and `exponential` wall-function
               blending treatments:
          COMP: check backward compatibility for:
                `serial`
                `parallel`
                `serial restart`
                `parallel restart`
                computations in comparison to the following tutorials from v1906:
                `circuitBoardCooling  condensatingVessel  evaporationMultiComponent
                 hotRoom  movingBox  multiRegionHeaterRadiation  reverseBurner
                 solidQuenching2D`
          STYLE: simplify `forAll`s
      
          ENH: add new wall blending approaches into omegaWallFunction
               adds stepwise, max, binomial, and exponential wall function blending apprs.
               ensures/forces the backward compatibility:
                 - blended = true    (blending:BINOMIAL2) (default)
                 - blended = false   (blending:STEPWISE)
              simplifies forAlls
              deprecates objects:
                 - "blended" - use "blending::" options
                 - "includeG" - as was hardcoded

          - nutWallFunction
          - nutUWallFunction

                - parallel
                - serial restart

                - heatTransfer/buoyantSimpleFoam/buoyantCavity
                - compressible/rhoSimpleFoam/gasMixing/injectorPipe

        BUG: fix value-entry behaviour in atmBoundaryLayerInlet (fixes #1578)
        Without this change:
        - for serial-parallel computations, if `value` entry is available in
          an `atmBoundaryLayerInlet` BC, the theoretical ABL profile expressions
          are not computed, and the `value` entry content is used as a profile data
        - for parallel computations, if `value` entry is not available, `decomposePar`
          could not be executed.
        With this change:
        - assuming `value` entry is always be present, the use of `value` entry for
          the ABL profile specification is determined by a flag `initABL`
        - the default value of the optional flag `initABL` is `true`, but whenever
          `initABL=true` is executed, `initABL` is overwritten as `false` for the
          subsequent runs, so that `value` entry can be safely used.
        Thanks Per Jørgensen for the bug report.
