+Generates the shapes and then serializes them to a JSON file with a list of 
+vertices (`positions`) and a list of triangle faces (`cells`) that index into 
+the list of vertices. Suitable for input into [Three.js's 
+BufferGeometry](https://threejs.org/docs/#api/en/core/BufferGeometry) or 
+[regl](https://github.com/regl-project/regl/blob/gh-pages/example/camera.js).
+
+Icosahedrons can be generated significantly faster than Three.js's version in 
+JavaScript (which I pretty much copied into Rust).
+
+Trunacated icosahedrons (I call them hexspheres) are a bit slower to generate 
+since they are made by generating a icosahedron and then subdividing it into 
+hexagon and pentagon faces. I still have some work to do to improve that code.
+
+I'm still having issues rendering hexspheres of detail level 5 and higher and 
+icosahedrons of detail level of 7 and higher, so I'm not sure if those are 
+accurate.
