- Removed the camera 'mode'
    - The (old) static camera was only appropriate when parallel
      projection was inactive, and the view was centred at (0 0 0)
    - Camera input now always requires 'position' and 'focalPoint'
    - Clip box is now optional.  Note that this is applied after the
      camera
      set-up and so will override the camera position
    - View angle is only appropriate when not using parallel projection
    - Zoom now required, applied after all other operations
      - 1 = do nothing, >1 = zoom in, <1 = zoom out

    Example input:

        camera
        {
            // Total number of frames to generate
            nFrameTotal 1;

            // Parallel projection flag
            parallelProjection no;

            // Optional clippling box
            clipBox     (-0.0206 -0.0254 -0.0005) (0.29 0.0254 0.0005);
            focalPoint  (0 0 0);
            up          (0 1 0);
            position    (0 0 1);
            viewAngle   20;
            zoom        1.1;
        }

- 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

Merge master changes/bugfixes into develop branch

See merge request !78

- update tutorial and adjust function object for updated infrastructure.

If the cloud was inactive, massTotal and SOI were needed even for steady Lagrangian
