Track graph
Included the track graph creation code in our repository.
Asks for user input to determine which track the kernel is running on and initializes the appropriate code.
Prints the name of a node in the loop (temp version) to show that the graph is being set up correctly.
Set up "TERMONLY" command line argument that compiles without CTS, so kernel can be uploaded to the RPis that are not connected to the train sets without freezing.
