changed to RSpec's expect syntax

I decided to change clearance to expect syntax for a project I was working on.  If, you want what I did, great!  If, not, you can just close this.

Please note, I have not done a poll request before.  If I have done it incorrectly, I apologize.
I did not take this to RSpect 3.  I took it to 2.99.  Did you want me to take it to the latest level?

I am back from my business trip so I can start working on this again.
