particleFoam, rhoParticleFoam: Replaced by solvers::functions with the fvModel functionObject

particleFoam has been superseded and replaced by the more general functions
solver module executed by the foamRun application:

    foamRun -solver functions

The incompressibleFluid solver specified by either the subSolver or if not
present the solver entry in the controlDict is instantiated to provide the
physical fields needed by fvModel functionObject in which the clouds fvModel is
selected to evolve the Lagrangian particles.  See:

    tutorials/modules/incompressibleFluid/hopperParticles
    tutorials/modules/incompressibleFluid/mixerVessel2DParticles

rhoParticleFoam has been superseded and replaced by the more general functions
solver module executed by the foamRun application:

    foamRun -solver functions

The isothermalFluid solver specified by either the subSolver or if not present
the solver entry in the controlDict is instantiated to provide the physical
fields needed by fvModel functionObject in which the clouds fvModel is selected
to evolve the Lagrangian particles.
