No handlers could be found for logger "oauth2client.util"

[GoogleCodeExporter]

[Use this form for both apiclient and oauth2client issues]

What steps will reproduce the problem?
1. Use oauth2client

What is the expected output? What do you see instead?
When using oauth2client, I often see the warning message:

No handlers could be found for logger "oauth2client.util"

I think the issue is related to the fact that this module actually gets an 
instance of the logger, rather than simply using the logging module to log 
errors, etc:

logger = logging.getLogger(__name__)

To prevent this issue, use the logging module, or specify a handler for the 
logger.

You should be configuring the logging in your application, once you do the 
warning message will go away:

See, for example, how this is done in the command-line samples:
