Detailed Description

 Collection of named slices

Slices are specified by a name and a length. If omitted, the length
default to one and the name to __0__ for the first unamed slice, __1__
for the second and so on.

Examples:
---------
>>> s = Structure([('a', 7), 3])
>>> print len(s)
10
>>> for name in s: print name
a
__0__
>>> print len(Structure([('a', 3), 'b']))
