      DESCRIPTION...
       THIS PROGRAM WILL LINEARLY INTERPOLATE BETWEEN TWO SPECIFIC 
       TIME INTERVAL, REPLACING ANYTHING FOUND BETWEEN THEM. AS MANY
       AS nombre_de_trous SUCH INTERVALS CAN BE TREATED. THE TIMESTEPS SHOULD
       BE IN ORDER, AS NO REWIND IS DONE BETWEEN SETS OF INTERVALS.
       FINALLY, XIN SHOULD NOT CONTAIN MORE THAN A SINGLE VARIABLE.
 
 
      INPUT PARAMETER...
 
       T1 (t1) = START OF INTERPOLATING INTERVAL
       T2 (t2) = END OF INTERPOLATING INTERVAL
       DT (t3) = NUMBER OF TIMESTEPS TO BE INSERTED
       KIND    = FLAG TO INDICATE METHOD OF TIME MEASUREMENT.
               = 0 ==> IBUF(2),T1,T2 AND T3 IN KOUNT UNITS.
               = 1 ==> IBUF(2),T1 AND T2 ARE IN THE FORMAT YYYYMMDDHH
                       AND T3 IS IN HOURS, NO LEAP YEARS.
               = 2 ==> IBUF(2),T1 AND T2 ARE IN THE FORMAT YYYYMMDDHHmm
                       AND T3 IS IN MINUTES AND AGAIN, NO LEAP YEARS.
               = 3 ==> IBUF(2),T1 AND T2 ARE IN THE FORMAT YYYYMMDDHH
                       AND T3 IS IN HOURS. BUT NOW, LEAP YEARS ARE
                       ACCOUNTED FOR.
               = 4 ==> IBUF(2),T1 AND T2 ARE IN THE FORMAT YYYYMMDDHHmm
                       AND T3 IS IN MINUTES AND AGAIN, LEAP YEARS
                       ARE ACCOUNTED FOR..
 
       NOTES: 1) KIND = 0,1 OR 2 DO NOT TAKE LEAP YEARS INTO ACCOUNT
                 AND ARE INTENDED FOR USE WITH MODEL OUTPUT.
              2) KIND CAN ONLY BE SPECIFIED ON THE COMMAND-LINE.
