5461634616 (doc) Add readme.md for coded-sequence library
This commit introduces a readme.md file to document the functionality and usage of the coded-sequence library. It covers the Elias Gamma code support, how sequences are encoded, and methods the library offers to query sequences, iterate over values, access data, and decode sequences.

b798f28443 (journal) Fixing journal encoding
Adjusting some bit widths for entry and record sizes to ensure these don't overflow, as this would corrupt the written journal.

36160988e2 (index) Integrate positions data with indexes WIP
This change integrates the new positions data with the forward and reverse indexes.

The ranking code is still only partially re-written.

4a8afa6b9f (index, WIP) Position data partially integrated with forward and reverse indexes.
There's no graceful way of doing this in small commits, pushing to avoid the risk of data loss.

0894822b68 (converter) Add position information to serialized document data
This is not hooked in yet, and the term metadata is still left intact.  It should probably shrink to a smaller representation (byte?) with the upcoming removal of the position mask.

0b60411e5f (query) Bugfix stopword issue
Add a new rule that crates an alternative path that omits a word if it's a stopword.

In queries where a stopword is present, and no query ngram expansion is possible, the query should not require the stopword to be present in the index, as this results in no search results being found.

daf2a8df54 (btree) Roll back optimization of queryDataWithIndex
It had been previously assumed that re-writing this function in the style of retain() would make it faster, but it had the opposite effect.

The reason why retain is so fast due to properties of the data that hold true when intersecting document lists, where long runs of adjacent documents are expected, but not when looking up the data associated with the already intersected documents, where the data is more sparse.

19163fa883 (array) Clean up the Array library
IntArray gets the YAGNI axe.   The array library had two implementations, one for longs which was used, and one for ints, which only ever saw bit rot.   Removing the latter, as all it ever did was clutter up the codebase and add technical debt.  If we need int arrays, we fork LongArray again (or add int capabilities to it)

Also cleaning up the interfaces, removing layers of redundant abstractions and adding javadocs.

Finally adding sz=2 specializations to the quick- and insertion sort algorithms.  It seems the JIT isn't optimizing these particularly well, this is an attempt to help it out a bit.

650f3843bb (array) Clean up search function jungle
Retire search functions that weren't used, including the native implementations.  Drop confusing suffixes on search function names.  Search functions no longer encode search misses as negative values.

Replaced binary search function with a branchless version that is much faster.

Cleaned up benchmark code.
