- list of versions as tuples
- constant calculated from picard.api_versions
- add tests
- skip tests if not enough elements (previous code didn't make sense anyway)
- get rid of useless ConfigSection.__config
- use name instead of full key (as section name is fixed)
- add support for qt type
- remove _convert_to_bool(), unneeded with qt type support
- use generators for candidates
- introduce picard.util.find_best_match() and sort_by_similarity() with tests
- partially revert change that removed sorted(), it was actually faster and cleaner
- use namedtuples to get rid of numeric indexes
- when no match, output max similarity, threshold and number of candidates to debug log
- make code easier to understand, using long names and namedtuple attributes, and simpler workflow
- use repr(best_match) for debug, as it provides all the needed info
- set values explicitly using namedtuple kw parameters
- use same prefix for namedtuples names, it eases searching through code
Typical debug output looks like:
```
