- this provides easily sortable names.

  The time information is available via the corresponding .series
  file, which can also be loaded directly with ParaView 5.5 or later.

  For further redundancy, time information is saved in the first XML
  comment inside of the .vtp files. For example,

      <!-- cloud=limestoneCloud1 time=0.005 index=200 -->

- The additional output generated by #calc directives in the
  controlDict or decomposeParDict causes issues for the RunFunctions
  extraction of 'application' and 'numberOfSubdomains'.

  Avoid by using -disableFunctionEntries, which also has the side-effect
  of disabling '#include'.

- major() and minor() are GNU macros in sys/sysmacros.h
  and generates warning on some systems (eg, Ubuntu 18.04)

  use getMajor() and getMinor() as method names instead.

- corrected the mass based correction and updated the misleading function
  arguments

- moved the option to the optimisation switches, e.g.:

    OptimisationSwitches
    {
        experimentalDdtCorr 1;
    }

- default remains off/no (0)

- in places where we use std::cerr instead or Warning or FatalError.
  We only want messages from one process though.

ENH: vtkCloud function object (issue #866)

See merge request OpenFOAM-plus!206

ENH: add foamRestoreFields utility (issue #877)

See merge request OpenFOAM-plus!207

- writes lagrangian data in VTP format during a simulation.
  In parallel, all data are written from the master.

- support VTP input in functionObjectCloud scene element

- additional fallback lookup of cloud information from state properties
  instead of cloud OutputProperties

- "Restore" field names by removing the ending.
  Useful, for example, to change a UMean to U field for further
  calculation.

- for Darwin, mention that clang is the only compiler configured

- adjust comments

version on a switch.  See #867

By default the code will use the same form as previous versions

To use the experimental version integrated from openfoam.org commit
da787200 set the info switch in the controlDict:

    InfoSwitches
    {
        experimentalDdtCorr 1;
    }

- when the iso-surface (eg, a cut plane, or distanceSurface) passes
  exactly through the cell centre, zero-sized triangles can occur.
  These should be merged away.

- change "\%" -> "%" in plain string
