13 '''Initialize static function variables to for use within a function. 

14 

15 This function is used as a decorator which allows for the initialization of 

16 static local variables for use within a function. It is used like: 

17 

18 @static_vars(counter=0) 

19 def foo(): 

20 foo.counter += 1 

21 print "Counter is %d" % foo.counter 

22 

23 This is used from:

26 Parameters 

27 ---------- 

28 Initialized static local variables.
