code: function delegateCommand(command) {
          var xformedArgs = [],
              origArgs = Array.prototype.slice.call(arguments, 1),
              retVal;
  
          transformVariables(origArgs, xformedArgs);
  
          retVal = uploader()[command].apply(uploader(), xformedArgs);
  
          return maybeWrapInJquery(retVal);
      }
docs: Assuming we have already verified that this is a valid command, call the associated function in the underlying Fine Uploader instance (passing along the arguments from the caller) and return the result of the call back to the caller
