 """
 Slicer(list) takes a list as argument. When a Slicer
 object is subscribted it returns a sublist of the list.
 For example:

 s = Slicer(range(0,64))
 s[0]                  => [0]
 s[0,2]                => [0,2]
 s[0:2]                => [0,1]
 s[0:2,4]              => [0,1,4]
 s[0:4:2]              => [0,2,4]
 s[0:2,4:6]            => [0,1,4,5]
