#593 Allow annotations on discrete variables
- Best to review per commit.
- Allow annotations on discrete variables.
- No more column-aligned code generation in CIF code generator for discrete and continuous variables, for some target languages. Similar to input variables.
- CIF to CIF 'Anonymize names' transformation does not anonymize annotation names and argument names. Made that explicit in the documentation.
- Introduced virtual TOC headings for parts of the reference manual. Similar to language tutorial.
