Instructions to download and use

[bhowes-tt]

@ikeough - This repo needs a wiki page that tells the user how to download and use RTF. As of last week when we were working through the EnergyAnalysisForDynamo test setup, I had to:

• Download and install nUnit 2.6.3
• Download the installer from this repo - tell n00bs like me how to download the raw installer, not the html file that github serves up
• Run the installer
• Run the program, point to a test assembly and provide additional paths for assembly resolution
• save an XML file representing the RTF setup so you can load a configuration in the future.

Also please show how to debug tests as RTF runs them using Visual Studio.
