https://github.com/nasa/nos3/issues/149 - Fix initialization of bus_type.

https://github.com/nasa/nos3/issues/150 - Make UDP more robust. Make input parsing more robust by tokenizing. Trim and upper case strings where appropriate. Fix prompt to include active connection name in short prompt.

https://github.com/nasa/nos3/issues/150 - Overwrite the newline with the null terminator.

https://github.com/nasa/nos3/issues/150 - Separate handle_input and handle_udp so that only one is used at a time in the executable/thread/library.

https://github.com/nasa/nos3/issues/150 - Begin adding in handle_udp() functionality. Partly working but not all working yet. Need port to be configurable via config file; handle commands with no returned string; decide if/how to have terminal and UDP interface have different settings.

https://github.com/nasa/nos3/issues/150 - Change process_command to return a string of what it used to print to cout. If the returned string is "QUIT", terminate the sim terminal application.
