       UR::DataSource::RDBMS::BitmapIndex - metadata about a data source's bitmap indexes


       This class represents instances of bitmap indexes in a data source.  They are maintained
       by 'ur update classes' and stored in the namespace's MetaDB.

       The existence of bitmap indexes in a datasource affects SQL generation during a Context
       commit.  Oracle's implementation requires a table covered by a bitmap index to be locked
       while it is being updated.
