Overview

This class understands how jobs fit together as a cohesive unit. It does not know how to use them, but it knows how to group them together in a logical manner following some simple rules, such as:

- Jobs in a set should have unique names (unless the name is blank)
- Subsets of jobs can be extracted, by name, in constant time.
