Build a Salon Appointment Scheduler

For this lab, 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`
