/*
 CreateSeveralVMRs.qs
  This script is meant to create several VMR projects via a user interface.. The script can be run directly via menu > Scripts > Create_VMRs 
 or via doubleclicking on the function name 'Create_VMRs()' in the 'Defined Functions'  window of the Script Editor.
 The script does not require manual modifications, because a user interface for the script is provided. Pop-up dialogs will ask for necessary files and values.
