Allows Flash file references to be attached to models. Requires something
   like attachment_fu or paperclip on the server-side if you are using
   remote service provider.
    
   
Example
For attachment_fu use this:
    
   
    var ref:RxFileReference = new RxFileReference;
    
    
   For paperclip use this:
    
   
    var ref:RxFileReference = new RxFileReference("avatar")
     
    
   This will match has_file_attachment :avatar in your Ruby model.
    
   If you pick a different name adjust the argument to constructor accordintly.
