* tweak comments; change if to switch
* remove old SOPs, minor comment styling, fixed silly performance bug on rehash using the wrong bitsRequired (count vs node)
* first raw cut; some nocommits added; some tests fail
* tests pass!
* fix silly fallback hash bug
* remove SOPs; add some temporary debugging metrics
* add temporary tool to test FST performance across differing NodeHash sizes
* remove (now deleted) shouldShareNonSingletonNodes call from Lucene90BlockTreeTermsWriter
* add simple tool to render results table to GitHub MD
* add simple temporary tool to iterate all terms from a provided luceneutil wikipedia index and build an FST from them
* first cut at using packed ints for hash t able again
* add some nocommits; tweak test_all_sizes.py to new RAM usage approach; when half of the double barrel is full, allocate new primary hash at full size to save cost of continuously rehashing for a large FST
* switch to limit suffix hash by RAM usage not count (more intuitive for users); clean up some stale nocommits
* switch to more intuitive approximate RAM (mb) limit for allowed size of NodeHash
* nuke a few nocommits; a few more remain
* remove DO_PRINT_HASH_RAM
* no more FST pruning
* remove final nocommit: randomly change allowed NodeHash suffix RAM size in TestFSTs.testRealTerms
* remove SOP
* tidy
* delete temp utility tools
* remove dead (FST pruning) code
* add CHANGES entry; fix one missed fst.addNode -> fstCompiler.addNode during merge conflict resolution
* remove a mal-formed nocommit
* fold PR feedback
* fold feedback
* add gradle help test details on how to specify heap size for the test JVM; fix bogus assert (uncovered by Test2BFST); add TODO to Test2BFST anticipating building massive FSTs in small bounded RAM
* suppress sysout checks for Test2BFSTs; add helpful comment showing how to run it directly
* tidy
