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.

Fix various msvc compiler warnings. With msvc the compiler flags are explicit passed to nvcc with -Xcompiler.

As thrust is used in the gpu code, CUDA c++14 is required. Besides fixed compiler warnings in Parameter.cpp.

Remove some compiler warnings and added some cuda warning suppressions for the GridGenerator, as they are cluttering the build output.
