TODO LIST

Bugs, quirks, "features":
- When importing BibTeX entries, if a field is enclosed in quotes instead of 
  braces, the program does not recognize it (and bugs)
- Adding a paper via the form:  if you don't check Auto-add/merge, it tells it
  is undefined (warning that does nothing)
- When adding two entries (@inproceedings followed by matching @proceedings
  crossref), only the first is processed
- Authors with a "von" part have 0 paper when you click on their name, and the
  von part is not displayed (page author-details.php)

In the near future (easily implementable):
- Remove accolades when displaying title in normal view
- Store table names in config file instead of hard-coded; this could avoid
  eventual name clashes if a user installs daDrill in the same DB as something
  else
- After adding a paper, provide a link to this new paper; idem for an author
- Support deletion of papers and authors
- Support edition of authors
- Add a "tag" field to each paper, and export to bibtex file only marked items
- More complete search function
- Add other formats for displaying references
- Language is from a list of choices: make it an option instead of a free text 
  field
- Export/import whole database (via .bib file)
- When exporting the bibtex entry, include crossref if any
- Fancier error messages (better than using die)
- Add a category field to entries and restrict results to categories (see how it
  is handled in ptlogger)
- Add maintenance operations:
  - remove orphan authors
  - auto-add listed authors that are not in the author table
- Write documentation for installing and using

In the far future (will need more work):
- Automatic splitting of names:  support comma separated list of tokens
- Browse citation graph
- Support for Bibtex style sheets
