Making Python Modules example is outdated

[enrique-infinite-orbits]

Hi, I'm trying to build a simple python module to transform CmdForceInertial message into CmdForceBody message. I follow the guide in https://hanspeterschaub.info/basilisk/Learn/makingModules/pyModules.html, but it failed in the very first statements:

.basilik) enri@enri-ThinkPad-P50 ~/Documents/basilisk_IO (master)$ python making-pyModules.py 
Traceback (most recent call last):
  File "making-pyModules.py", line 23, in <module>
    from Basilisk.architecture import sysModel
ImportError: cannot import name 'sysModel' from 'Basilisk.architecture' (/home/enri/Documents/basilisk/dist3/Basilisk/architecture/__init__.py)

I found looking the class SysModel exists inside Basilisk.architecture.sys_model_task... but it seems that's not the right class to use a base class for my module, for it never calls the UpdateState method.

I'll post all the code related to what I'm doing, but first I wanted to check if there was an updated version on how to create quick python modules for basilisk to prototype some stuff.
