Usage

• first run - program called with the --init parameter with following:
  database: "student",
  login: "init",
  password: "qwerty"

python program.py < test1.init.json

Creates table Employee and user "app" with desired privileges.

WARNING: database "student" with password "qwerty" should be created in PostgreSQL before first run!

• next runs - the input contains in the first row the call to the open function with the following
  login: "app",
  password: "qwerty",
  and then calling any API functions except open and root.

python program.py < test1.in.json
