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.

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.

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