move velocity boundary conditions to BoundayConditions folder and deleted the following velocity boundary conditions:

BcVel27;
QVelDeviceCouette27;
QVelDevice1h27;
QVelDevCompPlusSlip27;
QVelDevCompThinWalls27;
QVelDevIncompHighNu27;
QVelDevCompHighNu27;
QVeloDevEQ27

moved interpolated NoSlip boundary conditions to BoundaryConditions Folder and deleted the following NoSlip BCs:

QDeviceCompThinWallsPartOne27;
QDevice3rdMomentsComp27;
QDeviceIncompHighNu27;
QDeviceCompHighNu27;

explicit functions to find advection diffusion / temperature Init, BCs etc.
