WIP: Index function last occurrence
This branch was tested by merging with branch first_autumn_frost
. The following issues remains:
-
proper metadata to distinguish between missing data and no occurrence (#93 (closed)) -
day-of-year is counted from beginning of the season, not beginning of the year (#94 (closed)) -
the first_autumn_frost
is anannual
index (not a seasonal one) (#95 (closed))
