Bugfix: ALACRITY transform plugin now correctly computes groupsize growth rate when using a compressed inverted index
Generalized the query test script to allow multiple indexing configurations per query engine during the test
Added more printing of commands in 19_query.sh
Merge branch 'adios-query-test-diff-index-configs' into adios-query

Integrated an extended 19_query.sh test case that includes multiple indexing configurations per query engine.

Specifically, ALACRITY is now tested using both compressed and uncompressed indexes. At this time there is a
bug with compressed index querying that has been identified.

Also fixes a bug in ADIOS groupsize upper bound calculation for ALACRITY compressed indexes.
