Auto Vectorize Decorator

def vectorize(f):

 Allows a traditionnal python function to be called with
 iterables arguments.

 So when you call func([array]) it will do the iteration for you,
 call func() for each element in array, and return an array.

 All arguments must be iterable, if you want to pass something else,
 use a keyword argument.
