I understand that there is a new method to configure cFE that obviates the need for the headers. I was unable to find documentation on how to setup and run that. This PR does not address any necessary changes that would be needed for that method.

Also, this change implies that MAX_SIMULTANEOUS_LOADS can be set to 1. However, doing so breaks some old unit tests. I can address that in a follow-up PR.
