Examples

>>> # scalars
>>> i, s = 5, 'string'                                                      
>>> # 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)                                  
>>> ses = Session({'i': i, 's': s, 'a': a, 'b': b, 'a01': a01,
...                'arr1': arr1, 'arr2': arr2})                             
>>> # metadata
>>> ses.meta.title = 'my title'
