Server-based installation

To install the Dash-based GUI for this project on a new server or virtual machine, using the following steps:

Install needed system packages:

sudo apt install htop byobu apache2 libapache2-mod-wsgi-py3 git man minizinc python3-pip

Install needed python packages (for the root user)
```
sudo pip3 install dash pandas
```
Install NREL's System Advisor Model, version 2021-12-01
```
wget -Osam.run https://sam.nrel.gov/download/version-2021-12-01/65-sam-2020-11-29-for-linux/file.html
sudo ./sam.run
```
This will install the files in /opt/SAM/2020-11-29 (there seems to be a problem with the version numbers here!)
Install Minizinc from the official packages (Ubuntu's version may be missing some features)
Edit the file apache2/indust.re.conf to indicate the locations where the repository is located on your machine (we used /srv/indust.re)

Create a symlink to the above file, then enable the site, via

cd /etc/apache/sites-available
sudo ln -s /path/to/apache2/indust.re.conf
sudo a2ensite indust.re

Restart apache, systemctl restart apache2
Open the (ServerAlias as listed in apache2/indust.re.conf) site in your browser.
Chek apache2/indust.re.conf for the location of the error log files. In case of the presence of {APACHE_LOG_DIR} in the path to error log file, the location is configured using APACHE_LOG_DIR environment variable, which is defined in /etc/apache2/envvars.
Once you find the full path to the error log file, use tail -f to monitor the errors generated by apache: e.g. sudo tail -f /var/log/apache2$SUFFIX/indust.re-error.log.
