  Examples

      >>> import spacepy.datamodel as dm
      >>> import spacepy.toolbox as tb
      >>> a = dm.SpaceData()
      >>> a['1'] = dm.SpaceData(dog = 5, pig = dm.SpaceData(fish=dm.SpaceData(a='carp', b='perch')))
      >>> a['4'] = dm.SpaceData(cat = 'kitty')
      >>> a['5'] = 4
      >>> a.tree()
