0.9.8

• Support for 3mf file format in export.
• Choose a sensible location when exporting files.
• Fix zero-length edges and zero-area triangles in input STL or polyhedron.
• Added $fe variable which calculates fragments based on tolerance.
• Correct parameter name for polyhedron "surfaces" -> "faces".
• Basic implementation of mesh simplification.
• Added more tests for polygon and fix for empty polygon.
• Implemented normal$() module to show orthogonals to facets.
• Better detection of binary STL.
• Basic implementation of children() module.
• Let the align function can take a vector.
• Allow norm function to be applied to numbers and complex values.
• Fix inverse trig functions.
• Ang function can now return the axis and angle between two vectors.
• Implemented cross function and operator.
• Result of undefined binary operation should be undef.
• Allow relative positioning by letting primitives have children.
• Fix GL viewer, calculate normals with double.
• Allow concatentation with undef to yield a result.
  e.g. a=[]; no longer needed before to make a~=[1,2,3]; work.
• Implemented export to nef.
• Basic caching of primitives.
• Hook the view menu actions up to appropriate views.
