When building import files for companion specifications, one can export editable ConformanceGroups with the option "ExportConformanceUnits" from the context menu of the ConformanceGroup. For libraries however, there is no such option, which makes it necessary to temporarily add library scripts as a ConformanceGroup, export them and then manually create the according 'Library' xml element from the result to add to the CS-Import file.
To simplify this process, a function to export library folders similar to the "ExportConformanceUnits" function should be added to the CTT.
