Title: Function is called in two modules
Goal: Reorder the parameters of the function `foo/2' that has calling places in 
      two modules based on the new order `[2,1]'.
Parameters: [{file,"test4.erl"},{position,48},{order,[2,1]}].
Documentation: In this test case, the parameter of function `foo/2'
 are to be reordered based on the new list. The first parameter of
 the function becomes the last one, and the last comes first. This transformation 
 has to be performed in all modules where the function is called. The refactoring 
 tool has to handle the qualified function calls, too. Obviously, the changes
 apply to those modules only which are in the refactorerl database.
