add pressure filter kernel with one phase field / add double ghost layer connectors for two distributions and pressure

fix viscosity correction  and optimize muParser variable definition in MultiphaseTwoPhaseFieldsPressureFilterLBMKernel

fix bug and remove redundant initialisation in MultiphaseSetKernelBlockVisitor / remove unused parameter in MultiphaseInitDistributionsBlockVisitor

fix an issue with initialization  of beta and kappa parameters in MultiphaseTwoPhaseFieldsPressureFilterLBMKernel after restarting, need global refactoring kernel parameters

Pressure filter and pressure gradient computed so that boundary conditions can be used. Everything is limited to a single block.

Velocity formulation with filtered pressure and handmade periodic boundary conditions. WORKS ONLY WITH ONE BLOCK! No other boundary conditions.

Velocity fomulation without viscosity correction and no output for pressure and wrong output for velocity

due to the changes in the kernel factory the includes and calls in the numerical test framework are also changed

changed the naming of the missing Classes (Strategies) and added the chimera kernel from the open source code

fix the issue in FullVectorConnector derived classes: add initialization function of base class in derived classes

MultiphaseVelocityBCAlgorithm::applyBC(): vleocity in phase field taken from getBoundaryVelocityX1(). There is still something wrong as the actual velocity in the simulation is much higher than set in the input file!
