title: Is it possible to have NSwag ignore a controller?
body: <p>I used NSwag to generate a client for a single controller; I needed it as its own separate client.  I would like for it to be ignored when the Swagger specification is generated in the future.</p>
  
  <p>I tried adding this attribute at the top of the controller but it is still being noted in the specification:
  <code>[ApiExplorerSettings(IgnoreApi = true)]</code></p>
  
  <p>My controller is implementing the standard <code>Microsoft.AspNetCore.Mvc.Controller</code> class.</p>
