26902 Initial code review

Created a branch from the very first commit to be able to review the whole code written so far.
This does not mean that a merge should be done after the review is done, this is a "dummy" pull request.
That's a great comment explaining in details how things are being run. May be a small add-on would be to say : "The multi-launch-app bootstrap method ( for example ) .....", making clearer that there is a mechanism in the multi-launch-app that will call the startup/boostrap.py file ?
