Added MesoScaleCouplingCloud template and derived basicMesoScaleCoupingCloud.
New solvers icoMesoScaleCouplingFoam and mesoScaleCouplingMakeInitialFoam are created.
New particle force GravityWOBuoyancyForce is added.
Added new WallModel: stationaryWallLocalSpringSliderDashpot
Adjusted MesoScaleCouplingParcel and VoidFractionNumber to the OpenFOAM update
Small bug fixes
Added ExplicitPressureGradientForce.
Created gradP field in icoMesoScaleCouplingFoam.C accordingly.
Void fraction is averaged over the neighbouring cells.
pimpleCoupledKinematicParcelFoam is deleted
