title: Generating Multiple Typescript Files with NSwag
body: <p>I've just started looking into using NSwag to auto-generate typescript clients for a WebAPI project.  I've naively started with this simple build step:</p>
  
  <pre><code>nswag webapi2swagger /assembly:bin\MyProject.WebAPI.dll /output:Swagger.json
  nswag swagger2tsclient /input:Swagger.json /output:WebAPIs.ts
  </code></pre>
  
  <p>This works great...  maybe too great.  I've now got a 17000 line typescript file full of clients for every endpoint in the API.</p>
  
  <p>I know I could specify individual classes or controllers for nswag to generate, but I'd like it to be automatic for new controllers as we continue to build the system.  Ideally, I'd probably be best served with a set of typescript files where each file represented a single controller.</p>
  
  <p>Does anyone know how I might use the command line tools to break up the output that way?</p>
