Change Details

`test/index.js` has become an unwieldy catch-all of sorts, that could do with some cleanup and refactoring. Worth considering: * The elimination of string literal UUID representations. Ff an attribute was persisted using `dbu.testTidFromDate(new Date(datestr)))`, perform the subsequent assertion the same way, or better yet, reuse a well named variable. * Restructure the tests to be less monolithic with groupings that each encapsulate some subset of functionality. For example, static columns, order-by, secondary indexes, etc.
