The style rules can be checked using tests like below - but it should be made before merging to the Release Tests are from Pester.

I am happy to accept the PR up to commit ffa79be0eb86718ef3296b9f1d847b6970231505. The additional style rules enforced during the build isn't something I'd like to add.

I've gotten complaints that adding more functions to cover more of the API is overwhelming so I'm going to try to reduce the number of moving parts. I would like to reduce the barrier to entry. This would involve the following:

• Pester v4 support with the Because parameter to give better feedback
• No admin rights for build process
• Much better documentation
• Faster merging of PR (I think you'd appreciate that one!)

@ngetchell, I changed - some time ago - the code as you requested. Can you merge it now?

Not sure how I missed this. Thanks for the comment.
