Follow up London School TDD with more coding

I thought the last meeting was great, I really appreciated all the discussions. We didn't get very far with any actual coding in the london school TDD though, so I'd like to hold a follow up meeting where we spend a bit longer on the exercise.

There will likely be people who come who weren't at the last meeting, so I'll still spend some time at the start going over the same material as last time, but I intent to curtail the discussions in favour of more coding.

So for those who didn't come before, "London School TDD" is a term that's been used to describe the style of TDD that Steve Freeman and Nat Pryce use in their book "Growing Object Oriented Software, Guided by Tests" (GOOS). I think it is different from the kind of "Classic" TDD that people like Bob Martin and Kent Beck have written about in their books. We'll be discussing the differences and seeing if we can tackle a particular coding problem competently in either style.
