Added a version that will have a printed skin on the aerofoil.
Added a wheel module.
Deleted the directories that were made to separate the printed vs foam vs hybrid versions partly because GIT lost the history no matter how I copied the files and because having internal branches is maybe not the best structure. Instead I have made the aerofoil scad more library like and added a single new scad file for the printed skin version of the aerofoil.
Added a git ignore for stl and gcode files.
Started to layout the parts for test printing.
Added a better strut based horizontal stabaliser.
Added bushes for the wheel axil.
Increased the thickness of the version for printed skin on the aerofoil.
