Have fixed following issues:
1. Before insertion, I will check table for current highest value in id column and then insert.
2. I will use sql which build db schema when first running.
   For this, created a new sql script file - google_trends_db_schema.sql.
   Now, when running this Trends Scraper first, this automatically create empty db file from this sql script file.
3. I will make csv_archive folder and will put csvs in this subfolder.
