Description:
 def run(self):
 """Run the core loop of reading and writing configurations. This is where all the roaster magic occurs. On the initial run, we prime the roaster with some data to wake it up. Once awoke, we check our shared queue to identify if the user has passed any updated configuration. Once checked, start to read and write to the Hottop roaster as long as the exit signal has not been set. All steps are repeated after waiting for a specific time interval. There are also specialized routines built into this function that are controlled via events. These events are unique to the roasting process and pre-configure the system with a configuration, so the user doesn't need to do it themselves. :returns: None """
