-- Adds FileStoreI interface
-- Makes FileStore.java abstract superclass for FileStoreImpl (for Java)
and FileStoreJS (for JavaScript)
-- Passing all FeatureStoreJSTest TestNG tests
-- Passing all SequenceFeatureTest TestNG tests
-- About 10% faster for Java on TestNG tests.
-- full rendering in < 250 ms for JavaScript -- this is approximately 15
times faster than before I started this experiment.
