Template code doesn't make new sheets

[Landsil]

Currently you have to make a correctly named sheet for code to add columns and such.

It's an easy fix, I have to just find some time to do this.

Correct bit would be

  var sheet_name = spreadsheet.getSheetByName("sheet_name");
  if (sheet_name == undefined){
    spreadsheet.insertSheet().setName("sheet_name");
    var sheet_name = spreadsheet.getSheetByName("sheet_name");
  }```
