Implement logger

[da1910]

The architecture of the hooks we use to trim unnecessary files makes it difficult to work out what's wrong when template generation does not go as expected.

Cookiecutter provides a --verbose argument which enables much more logging. We should make sure this can be enabled by our scripts, and we should also make sure it enables logging within our template utilities.

For example I would like to know which files it removes/leaves when executing keep_files(), if I had access to this information I would have noticed the missing comma in my DESIRED_STRUCTURE list

Thanks for opening this @da1910. I agree with having the --verbose option and a logger for better debugging the whole rendering process.
