ENH: Added tutorials to show extraction of particle data from eulerian cases and subsequent injjection via lagrangian cases

Description
    Replays an set of particle data based on an injectedParticleCloud,
    using the assumption of one particle per parcel.

Usage
    \verbatim
    model1
    {
        type            injectedParticleInjection;
        SOI             0;
        massTotal       0; // Place holder only
        parcelBasisType fixed;
        nParticle       1; // 1 particle per parcel
        cloud           eulerianParticleCloud;
        positionOffset  (-0.025 2 -0.025);
    }
    \endverbatim

Description
    Interrogates an injectedParticleCloud to convert the raw particle
    data into a set of 'binned' injectors.

    The bins are set according to the particle \c tag property, from which:
    - diameters are converted into \c general distributions with a
      user-specified bin width
    - raw velocity and diameter data are resampled and stored to provide
      variations per injector

    The mass to inject can be set according to the raw input data mass total
    by using the \c applyDistributionMassTotal switch

Usage
    \verbatim
    model1
    {
        type            injectedParticleDistributionInjection;
        SOI             0;
        parcelBasisType mass;
        cloud           eulerianParticleCloud;
        positionOffset  (-0.025 2 -0.025);
        binWidth        0.1e-3;
        parcelsPerInjector 500;
        resampleSize    100;                    // optional
        applyDistributionMassTotal yes;

        // Placeholder only when using applyDistributionMassTotal
        massTotal       0;
    }
    \endverbatim

Note
    The each injector location is assumed to be operating under steady
    conditions, i.e. using a constant flow rate profile

ENH: Initial commit of new particleDistribution FO - generates 'general' distribution for lagrangian particle clouds

Merge branch 'feature-extract-eulerian-particles' of develop.openfoam.com:Development/OpenFOAM-plus into feature-extract-eulerian-particles

ENH: extractEulerianParticles FO - refactored to output a cloud of particles - distribution analysis to follow...

Generates discrete particle data from multiphase calculations by
interrogating the phase fraction field at a faceZone.

Data is written in raw form, i.e. per particle collected, with
as an optional binned distribution

- 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
