# purpose: create apsim-style management file from excel activity log
#
# created: june 14 2019
# last modified: june 19 (finished 2012 and 2013 CS rotation)
#                june 20 (fixed dates, added crop_class)
#                dec 1 2019 (loooking over it)
#
# notes: just trying to do plot 13 and 18 for 2012-2013 for now
#        need to update conversion factors (don't have internet now...)
#
# inputs: td_year-plot-trt-key, 
#         Marsden-activites-for-apsim.xlsx (in raw folder)
# outputs: td_op-plot13-2012-13
