closes #31

This looks good to me, but I think it should probably go through Caleb or Thorsten to approve I'm afraid (not sure I even have reviewer permissions here). But it all looks right to my limited understanding!

[asteurer]

Thank you @itowlson!

[asteurer]

@calebschoepp @itowlson I don't have merge permissions. Do one of you mind taking care of that for me?

[calebschoepp]

I wonder if we should make you a maintainer of this repo @asteurer, is that something you'd want?

[asteurer]

@calebschoepp I'd be open to that; however, I would appreciate some clarity around what will be expected of me as a maintainer for Akami-owned repos?

[itowlson]

@calebschoepp @asteurer maybe we should move it to the spinframework org and then there wouldn't be any vendor-related concern? (I am not fussed either way, just noting the option)

[asteurer]

That makes sense to me!

[calebschoepp]

Oh yeah... I was totally under the mistaken impression that this plugin was already under the spinframework org. We should move it there first like Ivan said.

I made an issue for that. If you're game Andrew please assign yourself to the issue.

CC @fibonacci1729 on what the steps are for transitioning this to the spinframework org.
