start test (xUnit) Infrastructure

- added first test project to the solution
- following some pattern identified in https://github.com/dotnet or BaGet
    - multiple test-csproj inside a folder "test(s)"
    - BaGet uses CamelCase for FolderName => "Tests" not "tests"
    - plural for tests ?
- in github/dotnet the "test" folde sometimes is brother of "src", sometimes is child of "src" => child of src selected!
-one xUnit -csproj per implementation-csproj
-use suffix ".Tests" for file, folder and default-namespace

implementation => tests
