public void ImportFromCTLFile( string fileName, bool loadAsCustom, string authority, string authorityMap )
Imports a collection of objects from the specified CTL file into the current DataSource.
If loadAsCustom is True, the data will be added to the custom DataSource; if no custom DataSource exists, an exception will be thrown. If loadAsCustom is False, the data will be added to the base DataSource.
If an object being imported has a GC code that matches an object already in the DataSource, it will be skipped.
