     1. Fixed a number of small bugs found in the last run at the SMT.  
        Made changes to tracker to make it ignore commands to go to 
        positions which are out of bounds (EL < 0 or > 90).  Since sun 
        avoidance can now be manually disabled, I made the 
        checkSunProximity() function  log a message every 10 minutes 
        if the sun avoidance is disabled.
     2. Added a flag ('wrapInhibit') to force servo to not use the 
        wrap, that is, to stay always within AZ = 0 to 360.  
        (necessary for the reset-encoders command.)  I still haven't 
        made it possible for the operator to force it into one wrap or 
        the other. 
     3. Put a log_open() call in the servo initialization.  Calls to 
        log_msg() are starting to appear at many places in the servo 
        program. Still need to make it respond to a 'purge log' 
        command. 
     4. Added many new variables to tstable so that information about 
        servo's operation is available to servo_control.
     5. Altered servo to be able to accept commands from the keyboard 
        and from sockets simultaneously.
     6. Made a simplification to the simulator code to make it derive 
        it's interrupt timing from the encoder A/D's even though it 
        doesn't use the data from the A/D's in that case.  This keeps 
        it in better sync with the servo program in the host since 
        they then use the same clock source.
     7. I learned that the DSP simulator crashes seem always to be 
        associated with a "send corrections" command which asks the 
        DSP to send the correction factors (offsets, amplitudes, 
        phases) for each encoder.  That corrections report is the 
        longest one. It needs to be changed to report on only one 
        encoder at a time instead of all 3.
