[#65313582] Finalized file name mapping classes in ABB.SrcML.
Updated NUnit for ABB.SrcML.Test to 2.6.3 (hint path was 2.6.1).
Changed the GeneratorArchive internals to use temp files with the correct file name extension. This helps with the DataArchive in ABB.SrcML.Data.
Converted the SrcMLArchiveMonitor to ArchiveMonitor and moved it to ABB.SrcML. Now it works as a general archive monitor.
Changed the DataGenerator and DataArchive to work with the new ArchiveMonitor. The DataArchive now has a "MonitoredArchive" that it uses to get srcML from. It then uses the DataGenerator which takes srcML as input and outputs srcML data.
Changed the short file name mapping to delete files that it can't read.
