Optional logger refactor

[walro]

Based on #13

The difference between this and #13 is:

• Slimmer diff compared to master when it comes to the specs
• Refactor specs to emphasize on the logger rather than the constructor (not 100% sure this is 100% better though, as the other specs are put on method level, now we have a higher-level of description here, sort of)

I was thinking if you agree with things here you could "pull the changes" in to #13 and we'll close this one

It is probably a good idea to simplify the diff a bit!

• Refactor specs to emphasize on the logger rather than the constructor (not 100% sure this is 100% better though, as the other specs are put on method level, now we have a higher-level of description here, sort of)

I'm not sure which option is better here. Like you say I chose to put the tests under #initialize to fit in with the rest, and if there is no clear "winner" I lean towards keeping it that way :)
