Creating a branch for FilterPushDown #89

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Purpose of code changes on this branch:
>>This version supports pushing Filter below Transform, Join, GroupBy, 
Co-group, Sort, and Merge expressions.

>> Most of the modified files involve propagating the mapping table that maps 
the output columns of an expression to the input columns.

After the review, I'll merge this branch into:
/trunk
