Pretty-printed code for the cqrs-starter-kit sample app.

This is the source code for the example presented in the cqrs.nu tutorial.  It was cloned from https://github.com/edumentab/cqrs-starter-kit) today.

The sources are just the CQRS stuff, and ignore the Tests or the web front end.  Though I did include the BDDTest.cs file, as that is the "magic" that makes the BDD tests so short.

The PDF was generated using a2ps:

```sh
$ cd cqrs-starter-kit/sample-app
$ find . -type f -name '*.cs' | \
   grep -v AssemblyInfo\.cs | grep -v Tests\.cs | grep -v WebFrontend | \
   xargs a2ps -Avirtual --pretty-print=csharp -o output.ps -MLetter -r
$ ps2pdf output.ps
$ mv output.pdf cqrs-starter-kit.sample-app.pdf
```
