What it does

When Installomator runs with a known label, the script will perform the following:

check the version installed with the version online. Only continue if it's different
download the latest version from the vendor
verify download is signed and notarized (fail if not)
compares Apple Developer Team ID with expected value (fail if no match)
when the application is running, prompt the user to quit or cancel (customizable)
dmg or other archives:
- extract the application and copy it to /Applications
- change the owner of the application to the current user (optional)
pkg files:
- when necessary, extract the pkg from the enclosing archive
- install the pkg with the installer tool
clean up the downloaded files
notify the user (also customizable)
restart the app (optional)
