Function Import-AutoPilotCSV(){
<#
.SYNOPSIS
Adds a batch of new devices into Windows Autopilot.
 
.DESCRIPTION
The Import-AutoPilotCSV cmdlet processes a list of new devices (contained in a CSV file) using a several of the other cmdlets included in this module. It is a convenient wrapper to handle the details. After the devices have been added, the cmdlet will continue to check the status of the import process. Once all devices have been processed (successfully or not) the cmdlet will complete. This can take several minutes, as the devices are processed by Intune as a background batch process.
 
.PARAMETER csvFile
The file containing the list of devices to be added.
 
.PARAMETER orderIdentifier
An optional identifier or tag that can be associated with this device, useful for grouping devices using Azure AD dynamic groups.
 
.EXAMPLE
Add a batch of devices to Windows Autopilot for the current Azure AD tenant.
