  /* LOGIC AND PROGRAM FLOW
   * You dont need to match the source file data to the target file data- When the Apps Script API updates a file
   * it overwrites everything- There is no inner file IDs to match -  You dont even need the target file data at all-
   * The source file data becomes the target file data-
   * You dont even care what the source file name is- it doesnt matter- whatever is in the source file is going to be
   * put into the target file no matter what
