/* The original version of the function below had Serial.prints()

   even in the middle of another Serial.print(), sometimes the sketch
   would lock up because we were trying to print in the middle of
   a print.
   
   So now we just set a flag and write to a string, and the master
   loop can deal with it when it wants.

/*-------------------------------------------------------------------

    The TI library calls this routine when asynchronous events happen.
    
    For example you tell the CC3000 to turn itself on and connect
    to an access point then your code can go on to do its own thing.
    When the CC3000 is done configuring itself (e.g. it gets an IP
    address from the DHCP server) it will call this routine so you
    can take appropriate action.
