Restructure the code base Move the core function code to a dedicate folder under namespace dust3d. Leave the application and UI code to application folder. Remove CGAL, use our own mesh boolean algorithm and triangulating code, should have less chance to crash on bad meshes. The overall performance of mesh combining is improved since some mesh validating code for CGAL is removed.
