-------------
* Abstracted the polling layer due to issues with select.poll on OS X
(https://github.com/crustymonkey/py-prefork-server/issues/8 thanks Abai)
The best poller for the system this is running on is now automatically
selected (epoll on modern linux, kqueue on BSD/OS X, etc.)
* Updated documentation to reflect changes with PEP 8 compliance
* Fixed a bug in the example code
* Other minor fixes
