title: Get FormCollection out controllerContext for Custom Model Binder
body: <p>I had a nice function that took my FormCollection (provided from the controller).  Now I want to do a model bind instead and have my model binder call that function and it needs the FormCollection.  For some reason I can find it.  I thought it would have been 
  <code>controllerContext.HttpContext.Request.Form</code></p>
