- 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

- enables future use of precision adaptors

- we know they have already protected by an is_contiguous check,
  so the class-memaccess warning/error can be suppressed.

- adjust known gcc/clang compiler versions

For example,

   $ someSolver -info-switch writeOptionalEntries

- note that values changed via the command-line are changed after the
  etc/controlDict entries, but *before* any case-local
  system/controlDict entries.

  However, in many testing cases the command-line options eliminate
  the need for such local file modifications.

ENH: cleanup handling of local debug switches in Time

- add as methods directly on simpleObjectRegistry to avoid code
  duplication

STYLE: adjust internal naming of ITstream parameters

- now reports the dictionary, entry, default. For example,

  Dictionary: <case>/0/nut.boundaryField.wall Entry: Cmu Default: 0.09
  Dictionary: <case>/0/nut.boundaryField.wall Entry: kappa Default: 0.41
  Dictionary: <case>/0/nut.boundaryField.wall Entry: E Default: 9.8

- suppress reporting for debug, optimisation switches since this
  generates extremely noisy output

- cannot rely on the entries having a keyword method

STYLE: apply consistent hash table sizing for debug objects
