extrudeExperimental() replaced by CSG.Polygon.solidFromSlices() and CSG.fromSlices()

I created CSG.Polygon.solidFromSlices() and CSG.fromSlices() based on extrudeExperimental code.
But they are more powerful because they deal with CSG.Polygon which can be 3D-transformed.
Look examples at http://tedbeer.net/demo3d/
