TASK ensda_pre

PURPOSE: Determines if the next cycle will have a flight observing the
hurricane inner core region.  Turns on ENSDA if so, and turns off if
not.  NOTE: Only one storm can have ENSDA turned on at a time.

Events:

  Ensda - if set, the ensemble should run, and if clear, the ensemble
    should not run.

The determination of whether to use ENSDA is done as follows:

1. If this cycle had an inner core observation flight by the Hurricane
   Hunter aircraft, then this cycle runs ENSDA.

2. If this cycle had no flight, then it runs ENSDA if the next cycle
   will have such a flight.  This is done by looking for a trigger file
   sent by the Aircraft Operations Center (AOC).  For details, see the
   ush/hwrf/ensda.py file within HWRF, specifically the
   read_trigger_file function.

3. If neither this cycle nor next cycle is under Hurricane Hunter
   aircraft observation, ENSDA is turned off.
