logging and verbosity

[dtmildebrath]

[#13 in old repository]

DLW: We should convert almost all output to logging to enable:

standardized inclusion of who is doing the output, and
easier control over verbosity
wrap TicTocTimer for easier logging

I see this issue has been open for a long time. I may be able to help with changing from print to Python logging. Is there still interest in this? I think extra information like the time from TicTocTimer, emitting class, rank, cylinder, strata, etc. could be added to the record for (optional) inclusion in the log message by the log formatter.
