+/// Basic (Naive) Mode
+/// ==================
+///
+/// This implementation hooks in through the XRay logging implementation
+/// framework. The Basic Mode implementation will keep appending to a file as
+/// soon as the thread-local buffers are full. It keeps minimal in-memory state
+/// and does the minimum filtering required to keep log files smaller.
