记录器

从根日志记录器进行日志记录：

>> from oar import logger as log
>> log.info("Init confiuration")
## [INFO] [2014-12-05 14:13:42,239] [oar]: Init confiuration

从您自己的子日志记录器进行日志记录：

>> from oar import get_logger
>> log = get_logger("oar.kao")
>> log.error("fatal error")
## [ERROR] [2014-12-05 14:14:32,116] [oar.kao]: fatal error
