.DESCRIPTION
This script is an alternative to the GACUTIL available in

.\Add-AssemblyToGlobalAssemblyCache.ps1 -AssemblyName C:\Temp\MyWorkflow.dll
This command will install the file MyWorkflow.dll from the C:\Temp directory in the GAC.
.EXAMPLE
Dir C:\MyWorkflowAssemblies | % {$_.Fullname} | .\Add-AssemblyToGlobalAssemblyCache.ps1
You can also pass the assembly filenames through the pipeline making it easy
to install several assemblies in one run. The command abobe will install
all assemblies from the directory C:\MyWorkflowAssemblies, run this command -
.PARAMETER AssemblyName
