Fixing a minor problem in MakeBundle, identified by TJ
TJ discovered that reading my documentation and following the instructions produces a cryptic failure. I'm fixing this.
- Adding a runtime_assert and error message if z1=0 to generate_atom_positions() in the helical bundle code.
- Updating documentation to make it clear that z1 and omega1 are not options that the user should normally set manually, unless he/she really knows what he/she is doing.
No unit or integration test changes expected.
