most functionality to splashdwon, find neutral and start mission. short timeouts still in code for testing, will adjust to go directly to sit_idle after splashdown

    Modified 2017-12-19 revA by Troy
        - Fixed OpenLog printing to include states and variable names.  Currently logs to LOG#####.TXT files
            1) Note: The OpenLog only starts a new log when it is power-cycled (with the MBED)
    Modified 2017-12-20 revA by Troy
        - Modified code to log every 1 second in current iteration
    Modified 2017-12-20 revB by Troy
        - Fixed bug where Dive depth was resetting to rise depth
    Modified 2017-12-21 revA by Troy
        - 2 minute timeout default
        - Added system time to MBED logger and OpenLog
        - Fixed bug where it was recording random keyboard presses (other FSM states)
        - Added the ability to save the batt and BCE PID config files
        - Fixed bug with FIND_NEUTRAL sub-FSM (command was not updating with each timer cycle)
