- All implemented tests now pass successfully!
 - Recognise and properly handle nested QueryBuilder invocations in more (hopefully all) cases.
 - Added ReplaceWithAttribute to Query.fs for easier recognising/handling of such invocations.
 - Removed a redundant attribute from QueryBuilder.RunAsValue
 - Added Nested.fs to the tests project and wrote 2 automated tests evaluating queries on nested structures
 - Modified Debug.prettyPrint so now it outputs even prettier text
 - Added Debug.printfn method to print to a log file. Useful for those long query text representations.
 - Added Debug.compExpr to compare 2 expression objects. Not used anywhere, no plans for it either
 - Fixed MSTest paths to correctly refer to the assemblies built in the script
