- only occurs in combination with distributedTriSurfaceMesh in snappy.

- workaround similar to that previously used for surfaceRedistributePar
  (issue #60).

Minor adjustment of incompressible motorBike tutorial to detect use of
distributedTriSurfaceMesh.

- there was a slight mix of MUST_READ and MUST_READ_IF_MODIFIED
  but with no obvious code to handle runtime modified values
  of the decomposition, or how this works with alternative
  dictionaries.

* boost 1_62_0 (Sept 2016)

* CGAL 4.9 (Sept 2016)
  - now has headers-only mode that could be interesting

* FFTW 3.3.5 (Jul 2016)

* openmpi 1.10.4 (Sept 2016)
  - the first openmpi 2.x release is also available, but too early to switch

* paraview 5.2.0 (Nov 2016)
  - builds without additional patching

STYLE: removed unneeded CMake environment variables

and single phase cases. Registration of the compressed flux in interFoam as it is
needed for the FO if used.

- in specific cases it can be useful to suppress searching the instances.
  For example, if one only wishes to check if a "points" is available at
  the given time instance, without searching backwards through all
  times.

- Avoids possible discrepancy when the user selects non-coincidental
  values for executeInterval and writeInterval.

- zeroGradient and ddt2 function objects

- this functionality will be more frequently used in the future,
  thus place in a commonly available location.

- A few without a 'cd' at the start.
  Use $(getApplication) directly in more places (for clarity).

- A few without a 'cd' at the start.
  Several remove files that are already covered by the cleanCase function.

- relocate to system/blockMeshDict, which avoids it being cleaned out
  accidentally

- Still needs more attention.

STYLE: fix minor typos in documentation

- consistently use SYSTEMOPENMPI for both sh and csh versions
  (inadvertently changed in ee5251a7).

  * args[int]   vs  args.args()[int]
  * args[word]  vs  args.options()[word]
  etc.

- purely cosmetic (documentation) changes
