Detailed Description

Decorate numpy arrays with a collection of named slices.

Array slices becomes accessible by their name. This is applicable to
nd array, although the same `Structure` is shared between all
dimensions.

Examples:
---------
>>> v = StructArray(np.zeros(10), [('a', 3), ('b', 7)])
>>> print v['a']
[ 0.  0.  0.]

>>> C = StructArray(np.zeros((10,10)), [('a', 2), ('b', 8)])
>>> print C['a', 'a']
[[ 0.  0.]
 [ 0.  0.]]
