+.Synopsis
+   Updates the Step Templates used on Deployment Processes to the latest versions
+.DESCRIPTION
+   Step templates can be updated from the library on Octopus, but that doesnt mean that the Deployment processes using that template will start using the latest version right away. Normally, the user would have to update the step template on each deployment process manually. This script takes care of that.
+.EXAMPLE
+   Update-StepTemplatesOnDeploymentProcesses -ActionTemplateID "ActionTemplates-3" -OctopusURI "http://localhost" -APIKey "API-RLMWLZBPMX5DRPLCRNZETFS4HA"
+.EXAMPLE
+   Update-StepTemplatesOnDeploymentProcesses -AllActionTemplates -OctopusURI "http://Octopusdeploy.MyCompany.com" -APIKey "API-TSET42BPMX5DRPLCRNZETFS4HA"
