Airfoil is now extruded perpendicular to the airflow through iterated extrusion. It's a bit of a hack, but it should work for my purposes.
Ignore all generated and compiled files.
Fixed some math errors.
Added a research abstract
Fixed some bend issues. Added more files to the gitignore file.

TODO:
- Cut ailerons
- Add endplates for wings
- Block electronic and motor placement
- Slice up model for laser cutting
Made extruding a function to ease further dev.
Reorganized the various methods into classes. More housekeeping is needed, but the finishing touches on the aileron code should come first.
