fixing a bug in the create sage database code and adding a status_update.py script which updates survival in database given a csv with plant status
Major update here includes a script to correct and then insert new data from the mid-summer field visit where only survival data was collected.  Script called 'mid_summer_status_update.py' which runs off of the mid_summer_all.csv file.  Needed to use a short R script to fill in the survival data--I only entered the zeros the first time.  The python script includes code to add the update to the database
