Killing the program

[datcomputerguy]

Right now we get zombie processes that seem to be a result of all of the different threads and processes that are being run. We need to program in an interpreter for keys like Ctrl+C and Ctrl+X so that they can actually kill the entire program and then there will be no need for the script that kills all of the existing python processes before running it again.
