Discussions with Margaret V. about POMS terms, etc.
We should have some new terms:
- (Campaign) Stages -- currently known as Layers
- Workflows -- abstract chains of Stages that can be instantiated into Campaigns
- Partitions -- slicing of Campaigns into subsets of data/processing
- Campaigns -- first class entities with parameters common accross Stages
- Steps/Submissions -- instantiation of campaign Stages in given partitions.
