[Numpy-discussion] basearray lives!

[Tim Hochberg]

After a fashion anyway. I implemented the simplest thing that could 
possibly work and I've left out some stuff that even I think we need 
(docstring, repr and str). Still it exists, ndarray inherits from it and 
some stuff seems to work automagically.

 >>> import numpy as n
 >>> ba = n.basearray([3,3], int, n.arange(9))
 >>> ba
<numpy.basearray object at 0x00B29690>
 >>> a = asarray(ba)
 >>> a
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])
 >>> a + ba
array([[ 0,  2,  4],
       [ 6,  8, 10],
       [12, 14, 16]])
 >>> isinstance(a, n.basearray)
True
 >>> type(ba)
<type 'numpy.basearray'>
 >>> type(a)
<type 'numpy.ndarray'>
 >>> len(dir(ba))
19
 >>> len(dir(a))
156


Travis: should I go ahead and check this into the trunk? It shouldn't 
interfear with anything. The only change to ndarray is the tp_base, 
which sets up the inheritance.
