Enhancements
- This release is mostly to add comments for the classes and minor code consistency cleanup. However, there are a few features as well 1) the "oneshot" epoll/kqueue requirement in the async dispatcher has been removed which gives a roughly 20% perf boost. DispatchObjects now cache read/write/eof events which means that the re-arm system calls can be eliminated. This is something that libevent cannot currently do. OSX kqueue support was also added 2) A simple timing class wrapper has been added that makes timing a function call including destructor overhead possible from within the function 3) make the Log class levels more consistent with syslog 4) use clock_gettime() for *ticks() when available 5) additional Config set() functionality
