Mvc ActionResults for returning FixedLength or SeparatedValue files

This project is great for doing flat files!

I needed to be able to return files from an ASP.NET MVC action method, so I wrote a couple of ActionResult classes that wrap a mapper/data combination and write out the data to a file. This does incur a dependency on System.Web/System.Web.Mvc, but that is only a compile time dependency.

Hope this helps someone else out!
