# Tests to verify a dependency is installed and returns true/false. Does NOT check version. 
# Designed for use with my OS dependency packages but can be used for anything to verify that SOME VERISION 
# of the dependency is installed; i.e. Chocolatey v0.10.11 will continue trying to install a package even
# if the dependency fails installation. Using Test-Dependency you can verify the dependency package DID get 
# installed and abort if not. Example: Test-Dependency "dependency-windows10"
# You would typically run this sometime before Install-ChocolateyPackage
