   .Synopsis 
    Export the Edu Assignments data of a user in a set of classes specified in csv file.
    .DESCRIPTION
    The script reads the class details of user from input csv file. Get the assignments and submissions of each assignment and generates the assignment file(assignment.json) and report file(GetAssignmentsReport.csv). when extracting of submissions is done it updates the GetSubmissionsProcessed column to true for that specific class. If the script fails in between we can rerun the script with the same input file, because the file will be updated for last deletion of submission.
   .Example 
    .\Export-EduAssignments.ps1 -userClassDetailsFile <full path of user class details csv file>
   .Parameter userClassDetailsFile
   This is the csv file(userClassDetails.csv) which is the output of Get-UserClasses.ps1 script. This file have information about the user classes and whether the deletion and get submissions are processed. This value should be full path of the file(drive:\GDPR\userClassDetails.csv)
   .Notes 
   We need to have the Microsoft.IdentityModel.Clients.ActiveDirectory.dll and Microsoft.IdentityModel.Clients.ActiveDirectory.WindowsForms.dll are required
