- for finer control of the '-help' output text

- this also removes the '-newTimes' option cruft from appearing
  everywhere. reconstructPar and redistributePar are unaffected by this
  since they define their own -newTimes option independently.

Compilation problems on older compilers

This reverts commit baf3e931.

    UPtrList::set(const label i, T* ptr);

No-op if the new pointer value is identical to the current content.
This avoid memory management issues.

- useful for customizing the behaviour of white/black lists depending
  on the type of the match.

- same as !isPattern(), but can be more readable.

- add wordRe enum state 'UNKNOWN', which has the identical value as
  'DETECT' but used for a return value.

Setting up twoSimpleRotors tutorial for smooth pressure
fluctuations

- can now construct with READ_IF_PRESENT and use count() to determine
  if it was loaded. names() and sortedNames() for a collected overview.

- makes an easier overview of the rotation matrix coefficients
  (issue #863).

  Provided as a distinct commit for easier examination of the lines changed.

- improve handling of degenerate cases for the two-axes specification.

- the movable type is List&& or Field&&

- allows reuse for other purposes

- improved move constructors/assignments for fileName, string, etc

- simply combines (rootPath()/globalCaseName())

This fix changes how the intersections loop ignores previously
intersected faces. It now marks them by their index so that subsequent
iterations ignore them.

Before this change, after an intersection was found the start point was
advanced by a small amount to move the past the intersection. The
problem with this was if multiple boundary faces or the end point were
in close proximity to the intersection then the move forward might span
them. This could lead to intersections being missed or counted multiple
times, in some cases indefinitely.

Merge branch 'wp3-directional-refinement' of develop.openfoam.com:/Customer-VWG/OpenFOAM-plus into wp3-directional-refinement

ENH: fieldMinMax function object - updated for case where there are no cells on a local processor, e.g. CHT

- Can now retrieve or set a column/row of a tensor.
  Either compile-time or run-time checks.

  Get
     t.col<1>();   t.col(1);
     t.row<1>();   t.row(1);

  Set
     t.col<1>(vec);   t.col(1,vec);
     t.row<1>(vec);   t.row(1,vec);

  The templated versions are compile-time checked

     t.col<3>();
     t.col<3>(vec);

  The parameter versions are run-time checked

     t.col(3);
     t.col(3,vec);

ENH: provide named access to tensor/tensor inner product as inner()
