Plus fixed a bug that would set span to 0

Cp is not written since VTK changed the name of their function. Writting cp slices works with VTK 9.3.0

Boundary layer c++ objects are created in python with swig and are manipulated by the interface. The initial condition of the viscous solver was changed. All test cases have been adapted. A decrease in the number of iterations is globally observed. Results are slightly improved especially for the RAE validation case.

Adding scipy before script

Added test case on the rae2822 3D finite wing thattests the 3D functionnalities of the code with vtk writing

Added vtk support in Dart api. Modified writing of boundary layer slices and introduced new argument of blast - writeSlices - which indicates vtk where to extract cps. The feature is not yet available for the boundary layer slices as this would require interpolation in the viscous solver.

Added the script, the lfs mesh for the inviscid calculation and the geo file to generate the viscous (structured) surface mesh. Minor changes in the interfaces, in particular associating different names to the different sections if needed.

Fixed API, dart interface and prevented segfault if the number of sections is not imposed correctly.

Contains 2D and 3D developements as well as the api.
