[heuermh]

Suggestions for repository cleanup:

rename Gnocchi-test → gnocchi-test
remove Gnocchi-test/src/main/scala/org/maventest
remove Gnocchi-test/test/scala/samples
remove TestDataResults or move into gnocchi-test/src/test/resources
remove gnocchi-cli/.src
remove gnocchi-cli/TestDataResults or move into gnocchi-cli/src/test/resources
remove gnocchi-cli/parquetFiles or move into gnocchi-cli/src/test/resources
remove gnocchi-cli/src/test/resources/metastore_db
remove metastore_db
remove parquetFiles or move into gnocchi-test/src/test/resources
remove parquetVersion or move into gnocchi-test/src/test/resources
remove testData or move into gnocchi-test/src/test/resources
move ADAMKryoRegistrator.scala into gnocchi-core/src/main/scala hierarchy
move GnocchiFunSuite.scala into gnocchi-core/src/test/scala hierarchy
remove Gnocchi_README.md
move fixPheno4Gnocchi.py into bin or scripts
move fixVCF4Gnocchi.py into bin or scripts
remove gnocchi-parent.iml

Note in general we try not to check in binary files for tests (e.g. Parquet folders), since we can't see diffs if test data ever need to change.
