Add python script for modifying the current and max days json file

* This will be ran daily in cron to update curr and max days. This will
  take input from a file that is generated by a form that was created
  to modify these values. These are comma separated fields. First is
  current record, second is max record. -1 value means that the number in
  json does not need to change and can be incremented. Anything > -1
  will set the counter to the given number, it will not increment it.
  The file is blanked after reading, and will default to -1 values if
  it is blank when reading again.
