Changed systemarchitecture by specifying what hardware parts are connected and summing up what STM and Odroid do

OOD draft follows the ideas written on the whiteboard.
Needs now to get fill by interfaces, ROS-Nodes, Threads and anything
else to get this code running.

Reducing OOA on functional point of view and ignoring implementation
details like "updateReady" or "isIdle()",

The whiteboard drawings from software architecture were digitalized into
a .tex file.

Add changes from 20.12. Logging-Block is not correctly designed. Maybe
there are some more direct ways to push data into Logging.

In addition the VeloxCar_Teilliste-2.xlsx has been copied from Assystem attachments.

 - a separate logging block is very usefull since, both the platoon
   controler and the ego-motion-model save interesting data

- Lanekeeping now gets data from EMM
- Added LogRequests from NET to EMM

Removed speed estimation module since it is integrated in the environment module.
