Using logging statements for development about tike HOT 4 OPEN

@dgursoy, This is what we talked about today. Any more thoughts?

Looks good. One concern is we need a level of control for the print statements though. Otherwise, it won't be structured and we can't use them easily afterwards. For example, if I print a "Hello World" somewhere, I may not want to have it in the txt file.

I guess you could use the __debug__ switch to save files instead. For example:

if __debug__:
    np.save('./debug_data/', some_data)

But also, if the user doesn't use the -O switch, it's better to dump a bunch of text to stdout instead of making files on their disk?

I think __debug__ can only be set before runtime, so we can't protect the user by setting it for them in the code.

Today I learned that the logger in a python library should be set to use the NullHandler. This is how it is set up for TomoPy and it allows the library to inherit whatever logging environment the end user has set up.
