RS( sQ Representation of possible resolution results of a package.
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.

The return value is a representation to the final resolution result. It
is a tuple subclass with three public members:
* `mapping`: A dict of resolved candidates. Each key is an identifier
of a requirement (as returned by the provider's `identify` method),
and the value is the resolved candidate.
* `graph`: A `DirectedGraph` instance representing the dependency tree.
The vertices are keys of `mapping`, and each edge represents *why*
a particular package is included. A special vertex `None` is
included to represent parents of user-supplied requirements.
* `criteria`: A dict of "criteria" that hold detailed information on
how edges in the graph are derived. Each key is an identifier of a
requirement, and the value is a `Criterion` instance.
The following exceptions may be raised if a resolution cannot be found:
* `ResolutionImpossible`: A resolution cannot be found for the given
combination of requirements. The `causes` attribute of the
exception is a list of (requirement, parent), giving the
requirements that could not be satisfied.
* `ResolutionTooDeep`: The dependency tree is too deeply nested and
the resolver gave up. This is usually caused by a circular
dependency, but you can try to resolve this by increasing the
`max_rounds` argument.
