code: def get_shape(self):
  		
  		return tuple(int(c.pcdata) for c in self.getElementsByTagName(ligolw.Dim.tagName))[::-1]
docs: Return a tuple of this array's dimensions.  This is done by
  		querying the Dim children.  Note that once it has been
  		created, it is also possible to examine an Array object's
  		.array attribute directly, and doing that is much faster.
