Modeling the IVR domain with algebraic data types

Why am I doing this?

In part 1 I talked about getting started on my graph-based IVR system. I started with modeling the authentication sub-graph. I wrote some Cypher queries to build the graph in Neo4j. In this part I am going to talk about how I modeled the graph in F# using algebraic data types, namely discriminated unions and tuples.

I use a combination of F#, xUnit, and FsUnit to do my unit testing on .NET. I want to run a database setup script at the start of some test modules. In this case, according to the xUnit documentation, I need to use IClassFixture (or ICollectionFixture). I recently wanted to figure out how to make this happen in my unit . . .
