Fibonacci tiles

This generates a Fibonacci tile - see Christoffel and Fibonacci Tiles Alexandre Blondin-Masse, Srecko Brlek, Ariane Garon, and Sebastien Labb https://link.springer.com/content/pdf/10.1007%2F978-3-642-04397-0_7.pdf These tiles tessellate. The inset parameter insets the tile to determine the interference in a 3D print or (negatively) the offset to account for the kerf in laser cutting. The Wikipedia article https://en.wikipedia.org/wiki/Fibonacci_word_fractal claims that there is a hole in the tessellation but I don't see that. My misreading of the Wikipedia article - this version is there called the Fibonacci snowflake and it does tile the plane. 2019-03-17 - I also missed out one order - now added (the jpgs are generated from another OpenSCAD script which does the tessellation) 2019-03-17 issue with offsetting tiles fixed
