data_ doesn't exist

Problem:
Tcl files don't run cuz when it asks for the data for the base station app code, it complains that there's not $data_

Fix:
Freaking, the number of nodes is set to 101, and that can't be changed to 5, the way I had it. number of nodes passed in must be 101 for now. don't know intricacies of what you'd need to do to change the base station's stuff.
