Here's the solution I showed at the CLD session today, Feb 6th 2014. Remember that this is just my way of doing it. I'm not saying it would get full points or anything.....but I do think it would get a pass.
For people that didn't attend todays session this might be a little confusing. But here's a little bit of a description:
I go through steps in my coding from Car wash 1.0 xxxxxxhs1 to Car wash 2.0 xxxxxxxhsFinal. All the steps in between is just steps in the development.
I know the documentation isn't going to be the best, if you have any questions just send me an email
