views support has been mostly completed. Documentation can be found in:

> Materialized views are useful as ways to store either alternate versions of 
> data (e.g. same data, different sort order) or derivatives of data sets (e.g. 
> commonly used aggregates).  It is useful to store these as materialized views 
> rather than as tables because it can give the optimizer the ability to 
> understand how data sets are related.
