with new C++11 driver, right after retrieving the first doc from first query, following message are prompt to stdout:

2016/05/18 15:15:30.0102: [19782]:     INFO:      cluster: SCRAM: authenticating "XXX" (step 1)
2016/05/18 15:15:30.0124: [19782]:     INFO:      cluster: SCRAM: authenticating "XXX" (step 2)
2016/05/18 15:15:30.0124: [19782]:     INFO:      cluster: SCRAM: authenticating "XXX" (step 3)
2016/05/18 15:15:30.0124: [19782]:     INFO:      cluster: SCRAM: "XXX" authenticated

Looks like it's some debug message that should not be kept in the library. I would like to suppress these information which is directly dumped to stdout. I expect mongocxx library not dump messages directly to stdout. Please let me know if I misunderstood. Please advice if this can be done without redirecting stdout with current library, or is there a plan to fix this soon.

Thanks!
