This entailed:
- changing the "flac" storage style option to "etc" to encompass both
flac and vorbis as the tags are very similar
- permitting multiple StorageStyles per field/format, to allow a
read-any/store-all approach to multiple field options
current metadata to be correct if it's complete
Previously, we were using the Munkres algorithm (minimum bipartite matching) to
order tracks intelligently only as a fallback if the current metadata was
paradoxical or incomplete. This was because of a concern about the performance
of the potentially-O(n^3) Munkres solver. However, it was found that (a) the
performance is actually not bad, taking on the order of 0.02 to perform a
matching, and (b) there was no recourse for the tagger to reorder tracks that
were legitimately in the wrong order. Now, we get intelligent reordering of
badly tagged music even when the metadata seems to be complete.
To retain some of the functionality of the old orderer, the track distance
metric was expanded to include a component reflecting the track index.
In doing this, another bug was discovered in the UI that showed the track name
differences based on an arbitrary ordering. Now, the tag_album function returns
a reordered items list with every candidate.
Also, new organization for tests and automatic loader. Fixed bugs uncovered by new tests.
