Classical rescaling of phase field distribution to 1/3 rho as common in Lee-literature. The source terms were removed from the moments and returned to the distributions based on the original code of Safari.

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!

Bug fix in density correct terms. Multiphase velocity BC has been simplified for this early stage of the development.

Implements surface tension following Hesam's code. Also corrects uninitialized variables in MultiphaseCumulantLBMKernel::findNeighbors . This might have influence on the contact angle. Initialization is now set to zero!

Implements pressure and stress correction for multiphase model with density contrast. Pressure is regularized and hence different from the form used by Safari and Fakahri. Surface tension is not implemented.

Implements cumulant phase field function and a passive incompressible momentum equation. The phase field is only coupled to the fluid velocity but there is no featback to the fluid. Only as a starting step for further developments.
