Version 0.4.0

Breaking changes:

Hayagriva now uses the Citation Style Language to encode formatting styles. This means that Hayagriva's own formatting styles have been deprecated.

For users:

• The YAML input format has changed.
  • Titles and formattable strings have been merged into one type. All formattable strings can have a shorthand now.
  • Formattable Strings do not have title-case and sentence-case keys anymore. shorthand has been renamed to short. To prevent changes of the text case of formattable strings, you can use braces. Enclose a part of a formattable string (or short) in {braces} to print it as-is.
  • The fields doi, isbn, and issn have been moved to serial-number which can now be a dictionary containing these and arbitrary other serial numbers like a pmid (PubMed ID) and arxiv (ArXiv Identifier).
  • The tweet entry type has been renamed to post.
  • All numeric variables can now also contains strings. Numbers can have string affixes.

Refer to the updated file format docs for examples.

For developers:

• To use a CSL style, you can either supply a CSL file or use an archive of provided styles with the archive feature.
• The from_yaml_str function will now return the new Library struct, with the entries within.
• The Database struct has been replaced by the easier to handle BibliographyDriver.
• We switched from yaml_rust to serde_yaml. The Entry now implements serde's Serialize and Deserialize traits. Hence, the from_yaml and to_yaml functions have been deleted.
• Brackets are no longer individually overridable. Instead, use the new CitePurpose.
• Entry::kind has been renamed to Entry::entry_type.
  • The citation styles AuthorTitle and Keys have been removed but can be realized with CSL.

This release fixes many bugs and makes Hayagriva a serious contender for reference management.

Other changes
