Title: Simple function with two parameters 
Goal: Reorder arguments of a simple function `foo/2' on the bases a list `[2,1]'.
Parameters: [{file,"test1.erl"},{position,43},{order,[2,1]}].
Documentation: In this test case, two parameters of the function
 are to be reordered on the basis of the order list. The last parameter of the
 function is a tuple. There is another function named foo in the module, but this 
 does not cause a problem, because its arity is 1. The refactoring can be 
 executed. The cursor is on "foo({X,Z},no)".
