ob-ipython don't use #+PROPERTY

[ghost]

ob-ipython don't use (add support):

#+PROPERTY: header-args:ipython  :session Calculus

If more than one session in different files, then add to the sections:

:PROPERTIES:
:header-args:ipython:  :session Calculus
:END:

or edit each

#+SOURCE_BLOCK

it is tedious.
