To Do

• [x] plan data structure
• [x] design
  • as a definition list
  • headwords are clickable
  • only display the headword (because these are lexeme-level relations)
• [x] add test data
  • [x] unidirectional / bidirectional (deverbal from: Arapaho, row #585)
  • [x] open set (compare, Chitimacha: hi-, pe-, ci-)
  • [x] enumerated set (animacy/transitivity matches)
• [x] add HTML
• [x] add CSS
  • [x] inline list of headwords
  • [x] use a headword style that will be consistent whenever headwords appear (maybe update the summary headword too)
• [x] add integration tests
