For example,
    surfaces
    (
        helmet
        {
            type        sampledTriSurfaceMesh;
            surface     motorBike-passenger-helmet.obj;
            source      cells;
            keepIds     true;  <<-- NEW
        }
    );

    This will create an additional "Ids" field that can be used to sort
    or as a faceMap to recover the original face order.

- cf. Line 224 of timeControl.C

- was erroneously using global sizing for offsets instead the processor
  local sizing.

STYLE: adjust variable naming, indentation for consistency

Takes cellZones and motionSolver per cellZone. See also dynamicMotionSolverListFvMesh.

ENH: outletMappedUniformInlet BC - Cp only calculated for patch and not entire domain; input keywords updated for consistency

- slightly odd. Building CGAL on other Linux systems have a proper
  ldd dependency for gmp/mpfr, but ubuntu doesn't

which provided warning about backward-compatibility issue with setting div
schemes for steady-state.  It caused confusion by generating incorrect warning
messages for compressible cases for which the 'bounded' should NOT be applied to
the 'div(phid,p)'.

to clarify purpose.

- if set in a dictionary and later removed, the intermediate value is
  retained rather than reverting to a normal default value.

- same applies for a few other function objects and their variables

- the interval for the next restart was not being adjusted when the
  file was reread, or when doing a complete simulation restart.

- propagate updated objectRegistry methods (eg, lookupObjectRef etc)
  into regionFunctionObject

Resolves bug-report http://bugs.openfoam.org/view.php?id=2372

ENH: improve objectRegistry functionality (issue #322)

- Recursive searching for objects within a registry is now optional
  (previous it was always done).

  A recursive search effectively blocks the construction of sub-sub-registries
  if their names are 'masked' by some parent level sub-registry with
  the same name! (BUG)

- Recursive search is now turned OFF by default, which makes it consistent
  with dictionary and probably causes the least number of surprises.

----
Various new convenience methods added:

lookupObjectRef()
- returns a non-const reference.
  For example,

      volScalarField& U = mesh().lookupObjectRef<volScalarField>("U");

  Instead of

      volScalarField& U = const_cast<volScalarField&>
      (
          mesh().lookupObject<volScalarField>("U")
      );

--
lookupObjectPtr()
- returns a const pointer, and nullptr on failure.
  For example,

      const volScalarField* Uptr = mesh().lookupObjectPtr<volScalarField>("U");
      if (Uptr)
      {
          const volScalarField& U = *Uptr;
          ...
      }

  Instead of

      if (mesh().foundObject<volScalarField>("U"))
      {
          const volScalarField& U = mesh().lookupObject<volScalarField>("U");
          ...
      }

--
lookupObjectRefPtr()
- returns a non-const pointer, and nullptr on failure.
  For example,

      volScalarField* Uptr = mesh().lookupObjectRefPtr<volScalarField>("U");
      if (Uptr)
      {
          volScalarField& U = *Uptr;  // use as reference
          (*Uptr) = ...;              // or use directly
      }

  Instead of

      if (mesh().foundObject<volScalarField>("U"))
      {
          volScalarField& U = const_cast<volScalarField&>
          (
              mesh().lookupObject<volScalarField>("U")
          );
      }

--
sortedNames()
- now works with template parameters and with regular expression
  matching as well.
  For example,

      wordList names  = mesh().sortedNames();
      wordList fields = mesh().sortedName<volScalarField>();

  Instead of

      wordList names  = mesh().sortedNames();
      wordList fields = mesh().names<volScalarField>();
      Foam::sort(fields);
