/* ============================ Use $recur_data array to write the master array ============================
// This used to use 5 different blocks to write the array... can it be reduced further?

For each recurrence date, an event may still cross day boundaries.  So we need to loop from the start_date for that recurrence to the end of that recurrence.
To generate $recur_data we mostly only paid attention to start times.

Now, a single event must be split into multiple master array values for each day on which it occurs

$hour and $minute are the values from the start_time, rounded to the nearest grid time.
