Some issues with the ML datasource schemas and batch predictions having more columns than predictions table specified.

There were a few bugs (2014 instead of 2013 in SQL query, missing column definition in predictions table) and prediction results explanation was a bit confusing (could use explanation that score = calculated probability and bestAnswer = threshold on score). However, great lab, good manual.

Another broken lab. 1. You need to change the s3 bucket creation. "flightdemo" will not be available to everyone since its obvisouly globally unique. So this also breaks the task completion. I never got passed 2/7 because i created a bucket called flightdemo5309/ 2. I accidently forgot to attach a policy to my first role. I was unable to correct it. I had to create another policy. I was unable to delete my bad role since i dont have perms. Not a bug, but was kind of annoying. 3. The Remote Desktop Client is a pain in the butt to use. The clipboard between the two machines kept breaking. I had to keep logging out of the remote desktop and bring all the way back up so the shared clipboard would work again. Since there are many steps requiring large amounts of text to be copied and pasted, typing it out is not desirable. When i got to the end and it broke for the nth time, i just gave up.
