// Some features:
// + optionally searches Abstracts and Reviews
// + allows RegExp searches
//   e.g. to search for entries between 1980 and 1989, type:  198[0-9]
//   e.g. for any entry ending with 'symmetry', type:  symmetry$
//   e.g. for all reftypes that are books: ^book$, or ^article$
//   e.g. for entries by either John or Doe, type john|doe
// + easy toggling of Abstract/Review/BibTeX
