YAY! audioDB::index_query_loop is now disentangled. Hardwired lsh_in_core to true, and invented a new QID flag for !lsh_exact. All tests continue to pass. The plans now: - extract the audiodb_query_spec() function from inside audioDB::query, and move audioDB::query (and the timestamps function) to audioDB.cpp; - write libtests/0036 and libtests/0037 in terms of audiodb_query_spec(); - rewrite all the other libtests in terms of audiodb_query_spec(); - delete audiodb_query() [ and maybe rename audiodb_query_spec(), I dunno]; - implement example bindings (probably to Lisp, because that's what I know best); - see if anyone other than me can work out how the API works. If not, provide documentation; - revise API in the light of user feedback.
