Allow to be imported as importable package

[alexsapran]

It would be nice to import Flog in my application as an importable package and trigger it from within my code.

This is useful when running some integration tests that flog is executed before the test.

Still in needs?

There is already PR: https://github.com/mingrammer/flog/pull/49

[alexsapran]

Excellent, I had not seen that PR; this can be considered fixed once #49 is merged.
