* make_index, make_summary, make_hotspots now return `str`, while make_index_references, make_summary_references, make_hotspots_references return `List[Reference]`. This is a consistent way to access the Reference objects in all cases.
0.9.14
* Initial release; features and implementation may change before 1.0.0; the manager facade should provide a consistent and backwards-compatible interface.
0.9.13
* Calculate hotspots (i.e. most referenced chapters) * Prevent matching e.g. '0.4' (no longer handle params in regular text). * Article Wiki integration: support for reference indexes in book-length documents.
0.9.7
* Add __.make_index() and __.make_summary(), incl. for demo. * `url_param()` and `url_escape()` replace `__.param()`. * Add __.template() to Manager, integrate with summary example. * More compact and efficient book names in regexp (group by prefixes).
0.9.6
* Remove unused functions and types. * Infer abbreviations in number ranges: 123-24 becomes 123-124. * Added merge_ranges() and combine_ranges() + tests. * Add range constructor functions for verses.
