New surface mesh is imposed in the viscous solver in 2D and stagnation point is recomputed at the first coupling iteration

Added adjoint for AoA and mesh in 2D. Nodes indices are now passed to the BoundaryLayer object

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.

Driver now computes the average position of the transition

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.

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.
