Traversal framework.

See:
Description

Interface Summary
BidirectionalTraversalDescription | Represents a description of a bidirectional traversal.
BidirectionalUniquenessFilter |
BranchCollisionDetector | In a bidirectional traversal there's one traversal from each start/end side and they will probably meet somewhere in the middle and the full paths are formed.
BranchOrderingPolicy | Creator of `BranchSelector` instances with a starting point to base the first decision on.
BranchSelector | Decides "where to go next" in a traversal.
BranchState<STATE> | Accessor for a state associated with a `TraversalBranch` during a traversal.
Evaluator | An Evaluator controls what's to be returned from a traversal and also how pruning is done.
InitialBranchState<STATE> | Factory for initial state of `TraversalBranch`es in a traversal.
InitialStateFactory<STATE> | Deprecated. use `InitialStateFactory.AsInitialBranchState` instead, which has got `InitialStateFactory.AsInitialBranchState.reverse()` as well.
PathEvaluator<STATE> | A PathEvaluator controls what's to be returned from a traversal and also how pruning is done.
PruneEvaluator | Deprecated. because of the introduction of `Evaluator` which combines `PruneEvaluator` and filtering (`Predicate` of `Path`s).
SideSelector | Dictates which side is the current side in a bidirectional traversal to traverse the next step for.
SideSelectorPolicy | A factory for `SideSelector`s.
TraversalBranch | Represents a `position` and a `RelationshipExpander` with a traversal context, for example parent and an iterator of relationships to go next.
TraversalContext | Provides a context for `TraversalBranch`es which they need to move further and report their progress.
TraversalDescription | Represents a description of a traversal.
TraversalMetadata | Provides metadata about a traversal.
Traverser | This interface represents the traverser which is used to step through the results of a traversal.
UniquenessFactory | Factory for `UniquenessFilter` filters, it can supply the created `UniquenessFilter` with an optional parameter which is up to the filter itself to validate and make sense of.
UniquenessFilter |

Class Summary
Evaluator.AsPathEvaluator<STATE> | Exposes an `Evaluator` as a `PathEvaluator`.
Evaluators | Common `Evaluator`s useful during common traversals.
InitialBranchState.Adapter<STATE> |
InitialBranchState.State<STATE> | Branch state evaluator for an initial state.
InitialStateFactory.AsInitialBranchState<STATE> | Wraps an `InitialStateFactory` in a `InitialBranchState`
PathEvaluator.Adapter<STATE> | Adapter for `PathEvaluator`.
Sorting | Provides some common traversal sorting, used by `TraversalDescription.sort(Comparator)`.

Enum Summary
Evaluation | Outcome of `Evaluator.evaluate(org.neo4j.graphdb.Path)`.
