Example:  I want to read in and process all the high priority rate data
	 that occured Sept. 24, 1997 8 am to 10 pm GMT.

--------------------------------------------------------------------------------
the test routine:

pro test2
        ; preliminary definitions for sis data
    common SisSymbols
 
    date = {AceTime}
    date.year = 1997
    date.month = 9
    date.day = 24
    date.hour = 8       ; 8 am
    date.min = 0
    date.sec = 0
    print, 'date = ', date
    secondsSince1996Start = cvttosec1996(date)
    print, 'secondsSince1996Start = ', secondsSince1996Start
 
    date.hour = 22      ; 10 pm
    secondsSince1996Stop = cvttosec1996(date)
    print, 'secondsSince1996Stop = ', secondsSince1996Stop
 
    structs = get_group_hi_rates_s(secondsSince1996Start, secondsSince1996Stop) 
 
    print, structs.Second1996
    help, structs
end
