Event loop integration

pycares can be integrated in an already existing event loop without much trouble. The examples folder contains several examples:

• cares-select.py: integration with plain select

• cares-poll.py: integration with plain poll

• cares-selectors.py: integration with the builtin selectors module

• cares-resolver.py: integration with the pyuv event loop

• cares-asyncio.py: integration with the asyncio framework

Additionally, Tornado provides integration with pycaes through a resolver module.
