The smallest setup

Six lines in Program.cs make a working CMS host:

var builder = WebApplication.CreateBuilder(args);
builder.AddRelatudeCMS().AddMvcRendering();

var app = builder.Build();
app.UseRelatudeCMS();
app.MapRelatudeCMS();
app.Run();

Call	What it does
`AddRelatudeCMS()`	adds Relatude.DB, the CMS settings, analytics and content routing, which turns a URL into a page or a stored file
`.AddMvcRendering()`	renders pages with MVC views and controllers; `.AddRazorPagesRendering()` adds Razor Pages
`UseRelatudeCMS()`	starts the database and its admin UI, and adds the analytics middleware
`MapRelatudeCMS()`	answers every URL the database knows: it renders the page or sends the file

The calls are in the global namespace, so they need no using.
