Group systems by software installed

################################################################################
# This script requires the JumpCloud PowerShell Module to run. Specifically, the
# JumpCloud PowerShell SDK Modules are required to run the system queries. To
# install the PowerShell Modules, enter the following line in a PWSH terminal:
# Install-Module JumpCloud
#
# To run this script, update the 'SoftwareTitle' to search for a software title
# match in the system insights tables. Optionally edit the group name variables
# if you would like to change the group names.
#
# This script will create two groups, based on the software title.
# AutoGroup-$softwareTitle-has - Mac/Windows systems that have the softwareTitle
# AutoGroup-$softwareTitle-missing - Mac/Windows systems that are missing the
# softwareTitle
#
# This script will search for software titles on Mac/Windows and return matches
# ex: Google Chrome on a system will match the $SoftwareTitle "Chrome" like the
# default example
#
# This script can be run multiple times. As systems update, they will be removed
# or added to the "has" or "missing" group depending on whether or not they have
# or do not have the software title in the $softwareTitle variable.
