Add msvc warning level W4 and removed most of the warnings. Some of the warnings are suppressed (see MSVC.cmake)

add test acoustic pulse for DLR-F16 simulation environment, add FLOAT64 / double support in WbWriterVtkXmlBinary / WbWriterVtkXmlASCII, bat only for writeOctsWithNodeData

- in header: typedefs for smart pointer usage

- completly switch to std::shared_ptr
- introduce IKernel Interface and CalculatorFactory
- extract Vector3D from UbMath
- introduce WriteObjectsCoProcessor

replace BCArray3D& with BCArray3DPtr
DLR-F16: working copy for Pheonix, MPIIORestartCoProcessor has a BUG! MPIIORestart3CoProcessor is reimplementation of MPIIORestartCoProcessor with bug fixing. Buf is fixed in MPIIORestart2CoProcessor.
add new implementations for MPIIORestartCoProcessor: MPIIORestart11CoProcessor and MPIIORestart21CoProcessor, which have separation in dataformat for blocks, data set and bc
Changed BCAlgorithm for object collection in BCProcessor
Fixed issue with GenBlocksGridVisitor

TransBlock to BCBlock
TransNode to BCNode

add acoustic pulse test
add MPIIORestartCoProcessor (n checkpoints to m processes)
add InitDistributionsWithInterpolationGridVisitor
add CompressibleOffsetMomentsInterpolationProcessor (refinement with bulk viscosity)

key is string now
