> This is the tracking bug for the work to add types to pig and rework the 
> execution pipeline.  Individual components of this work are covered in 
> subtasks.
> Functional and design specs for this work are:
> http://wiki.apache.org/pig/PigTypesFunctionalSpec
> http://wiki.apache.org/pig/PigTypesDesign
> http://wiki.apache.org/pig/PigExecutionModel
> This work is being done on the branch types, since it is large and 
> disruptive, and we want to be able to do incremental checkins without causing 
> issues for the trunk.
