* merging "schmoin" experiment with joining aggregations into regular "join" ↵Nick Kallen2008-01-217-20/+76
| | | | functionality; half-way done...
* completed initial functionality for joining with aggregation (the meaning of ↵Nick Kallen2008-01-2118-92/+152
| | | | which is joining on a subselect/derived table); the big change is the introduction of a #projections protected method; this is a private version of #attributes which preserves implementation information (e.g., the name of the function called)
* adding grouping functionality; added some dummy code ("Schmoin") for ↵Nick Kallen2008-01-1615-22/+169
