>>> # axes
>>> a, b = Axis("a=a0..a2"), Axis("b=b0..b2")
>>> # groups
>>> a01 = a['a0,a1'] >> 'a01'
>>> # arrays
>>> arr1, arr2 = ndtest((a, b)), ndtest(a)
>>> s = Session({'a': a, 'b': b, 'a01': a01, 'arr1': arr1, 'arr2': arr2})
>>> arr = s.get('arr1')
>>> arr
a\b  b0  b1  b2
 a0   0   1   2
 a1   3   4   5
 a2   6   7   8
>>> arr = s.get('arr4', zeros('a=a0,a1;b=b0,b1', dtype=int))
>>> arr
a\b  b0  b1
 a0   0   0
 a1   0   0
