This holds three attributes:

* `information` is a collection of `RequirementInformation` pairs.
      Each pair is a requirement contributing to this criterion, and the
      candidate that provides the requirement.
    * `incompatibilities` is a collection of all known not-to-work candidates
      to exclude from consideration.
    * `candidates` is a collection containing all possible candidates deducted
      from the union of contributing requirements and known incompatibilities.
      It should never be empty, except when the criterion is an attribute of a
      raised `RequirementsConflicted` (in which case it is always empty).

.. note::
        This class is intended to be externally immutable. **Do not** mutate
        any of its attribute containers.
