Scan an assembly in order to create a DataContractContentSerializer

Resolves #100.

Ah, I see. That's where we view things differently :)

The way I see it, this test is part of a TDD process. The *goal* of this particular process is to produce the `Scan` method. In my opinion, then, the `Scan` method is the System Under Test.

The rest is just verification.

Yes; and we *could* have, if we'd created two new implementations of `ITypeResolver`, instead of reusing `TypeResolutionTable` within the `CreateTypeResolver` methods... :)
