what is the point of including NUnit & VS Unit testing in the same project? KnowledgeExchangeWeb.Tests

@bennyb - I initially included the sites that are generated by the project wizard.  This by default is the VS unit testing.  With article 3 I have removed VS unit testing in favor of NUnit testing.  If you got both before and after you probably ended up with both frameworks.  I will remove the VS unit testing entirely today.
