Build a Salon Appointment Scheduler

This is one of the required projects to earn your certification. For this project, you will create an interactive Bash program that uses PostgreSQL to track the customers and appointments for your salon. # --instructions-- **Important:** After you pass all the project tests, save a dump of your database into a `salon.sql` file, as well as your `salon.sh` file, so you can complete step 2. There will be instructions how to do that within the virtual machine. # --notes-- Required files: `salon.sql`, `salon.sh`
