Installation Script for OpenEMS

This installation script automates the setup of OpenEMS on a server. It performs the following tasks:

1. Host Configuration: Prompts the user to enter the host name for the server. If no input is provided, it defaults to the current hostname.

2. UI Default Setting: Asks the user if they want to set the OpenEMS UI as the default for the server. If confirmed, it warns that this will override the default Nginx configuration.

3. Package Installation: Updates the package list and installs the required packages, including OpenJDK 17, Nginx, and Wget.

4. OpenEMS Service Setup: Downloads the OpenEMS system service configuration and sets up the necessary directories and files for OpenEMS.

5. Nginx Configuration: Sets up the Nginx server to serve the OpenEMS UI, including downloading the UI files and configuring the Nginx site.

6. Service Management: Reloads the systemd manager configuration, enables, and starts the OpenEMS service, and restarts Nginx to apply the new configuration.
