update to minor version! because here be breaking changes
added concept of local and remote caches (which changes the cache trait), as well as caching not found items. removes query. removes query2.execute.
the code works insofar as tests pass, but there is no testing of the caching yet.
added calls to the cache instrumentation method. added a test cache, and added that to the test tables, as well as turning off skip-cache in the tests. removed the unused putResultsLocal.
