Get rid of the global logger

[sHermanGriffiths]

Describe Your Changes

The use of the global logger resulted in the configuration of the logger in any project that uses the n2y package. This is obviously not the desired effect, as we want n2y users to be able to use our package and configure their logging system the way they would like.

How Did You Test It

I loaded n2y in a project and ensured that the project's logging configuration was used and not the n2y package's.

Looks good to me, just one minor comment. I always have to remind myself how Python logging works in situations like these!
