Goal: To make it easier to put our transcendence to the test.

To this end, I'm adding

• a new container tool: adminer.
• 2 files :
  • two2f_testing_db.csv
  • user_testing_db.csv

This addition allows you to quickly create an automatic database with 6 users (Jean, Guillaume, Charles, Valentin, Thilbaut and Jimmy).
