There are four main concepts in this package, each one modeled as a
class:
- A `WorkUnit` represents a sequence element.
- A `Producer` is responsible for generating a sequence of
`WorkUnit`s to be processed.
- A `Processor` is responsible for processing `WorkUnits`
individually.
- A `Consumer` is responsible for handling processed `WorkUnits`.
These concepts/objects are the building blocks of a
`ParallelSequenceProcessor`, which is depicted below.
The `ParallelSequenceProcessor` in this figure has been configured with
two *lanes* for priority `0` (lanes 1 and 2) and a single *lane* for
priority `1` (lane 3).
Unless specified otherwise, by setting `require_in_order=False`,
the `Consumer` receives processed `WorkUnit`s in the same order as
produced by the `Producer` directly above it (in the same lane). This
ordering is ensured by holding processed `WorkUnit`s until all units
produced before them have been processed and passed onto the
`Consumer`.
