- can assist diagnosing when things have gone wrong

- wmake -version, --version option (alias for -show-api)
  for consistency with standard system tools

- move left/right positions prior to substr

- fix typo

- now indicate that the dictionary entry is missing, not that it is
  an unknown function type.

- reduce code duplication, support returning multiple interpolations
  as a Field

- cleanup the run script syntax

- use sed instead of foamDictionary and avoid log file

- ensure consistent behaviour with plot script

GIT: added missing 0/k field : inlet values still need adjustment

- no stderr redirect needed:
    * 'command -v'

- no stdout/stderr redirect needed:
    * 'rm -f'

STYLE: consistent spacing after redirects

- min/max ops that only compare the first element

- this can help if using std algorithms that return a const reference
  such as std::min() does.

- building plugins with paraview-5.7 is quite different

- we don't need the GUI sort order of the values.

- define nut conditions explicitly, without fallback definition

- can be helpful, for example, when the refCast has been used on a
  boundary patch. Knowing which patch index triggered the problem
  helps with isolating the issue.

STYLE: renamed periodicHill createPlots -> plot for consistency

TUT: use nutLowReWallFunction for bump2D

- required for the new nutWallFuncs hierarchy
