If I use MigrateSourceCSV as a source instead of installing data into a mysql table, do I need to do anything special with $base_table, $base_table_id, $base_table_alias?  I noticed that the Civimigration class has these variables that may not make so much sense to use with a CSV source because they refer to parts of database tables.  Also, do I need to set $autoquery to false?
