fixed one error, now onto the next one
minor changes
merged in DTFThreads class code
Looks like the socket class is working in the server thread
component is working with a TCPSocket class in the server thread
added a 3rd control system, everything appears to be working correctly
Socket class appears to be working in both the server and sending threads
fixed bug in the update state method is the system 3 plant
small change to Makefile to make sure it correctly cleans up executables
